Waves Resources

Let’s start with a song!

and if you like that one, then this is Physics legend

this has got lots more information on the EM Spectrum

Waves Summary Notes

These are waves summary notes I’ve produced. Hope you like them. I’d appreciate someone telling me if a photodiode can detect gamma radiation!

Revision Mind Map

This is part of a series of brilliant Mind Maps made by Miss Milner for the N5 Physics Course. I’ve broken it up into sections so here are the waves mind maps!

Here are a list of current wave resources. I will add more as I go through them. Thanks to other schools if you have kindly supplied material. I really appreciate it as do my students.

Reflection is not in the N5 Course, but it is good to know about reflection!

waves-summary-notes-gairloch1 Some of these notes are for National 4, use with the content statements so you don’t spend too long learning the National 4 work.

vflambda-vdt This starts with a practical model that you can complete in class using the Virtual Physics/ Flash Learning. It then shows how v=f位 is equivalent to v=d/t. Finally some questions will let you practise what you know.

Waves Learning Outcome Questions

Here are the Waves Learning outcome questions which will help you through your revision. They can also be found in the Learning outcome section in the Course Material drop down menu. Answers are on here too, but copying from the answers is a pointless activity. Hopefully by completing all of these questions you will have produced an excellent set of revision notes from which to revise.

You can always use these in electronic version to answer the questions but DON’T think you’ll produce one set between you and copy!

One of the uses of UV radiation is a security feature of bank notes. Shining UV radiation on to the bank note causes them to fluoresce (the atoms in the material take in the UV radiation and re-emits it as light which we can see)

Look at how advanced the fluorescing shapes and colours are.

Experiments- Uses of UV to check the authenticity of bank notes

IR cameras are used by the police to track for criminals at night but they are also really useful to the fire brigade at finding people in smoked filled buildings, you can’t hide behind a bin bag and even a hand print can leave a “heat print”.

You can’t hide in a bin bag if someone has the IR camera on you!

Did you know you can be on the radio? Not very musical but it can drown out Radio Scotland.

Do try this at home, use cheese marshmallows or chocolate but you need to take the turntable out and DON’T put things on a metal tray!

The electromagnetic (em) spectrum is a collection of transverse waves that all travel at the same speed in air, the speed of light, 300 000 000 m/s. (equivalent to 7.5 times round the Earth every second)

One of the waves is VISIBLE LIGHT

A=amplitude 位 = wavelength

Others are RADIO & TV, MICROWAVE.

The others are INFRA-RED, ULTRA VIOLET, X-RAYS, GAMMA WAVES.

The only difference between each of these waves is their wavelength or frequency. They all fit the formula

Speed= frequency 脳 wavelength

v=f 位

The order is important and to remember it use the following rhyme!

Randy                  Radio & TV

Monkeys              Microwaves

Invade                 Infrared

Venezuela           Visible

Using                   Ultraviolet

Xylophone           X-rays

Gunships             Gamma

Period, T, is the time for one wave to pass a point and is measured in seconds.

Frequency, f is the number of waves being produced or passing a point per second. Frequency is measured in Hertz (Hz)

Here are lots of resources for you to check and practice. My utmost apologies if I have not credited people for sending this material. As soon as I know who you are I will thank you personally.

REVISION GAMES FOR WAVES

Waves Definitions

Here are some definitions to learn for the waves topic. Remember you must be able to spell:

REFLECT, DIFFRACT and REFRACT

Term Definition
Amplitude (A) the distance from the middle of the wave to the top (or the bottom) measured in metres. Maximum displacement from the mean position!
amplitude, (A) maximum disturbance of the particles in a wave. (or distance from middle to top of wave) (m)
Angle of incidence 聽the angle between an incident ray and the normal (a line perpendicular to the reflecting surface at the point of incidence) (掳)
Angle of reflection 聽the angle between a reflected ray and the normal (掳)
Angle of refraction the angle between the light ray in the more optically dense material and the normal. (掳)
Critical angle The critical angle is the angle of incidence above which total internal reflection occurs. (掳)
Diffraction occurs when wave meet a barrier, the waves bend around an obstacle. Long waves diffract more thank short waves.
Energy and waves Waves transmit energy. The greater the amplitude the more energy is transferred.
Frequency, (f) the number of waves per second. Frequency is measured in hertz (Hz).
Frequency, (f) 聽number of waves produced or passing a point per second. (Hertz or Hz)
Law of reflection The angle of incidence = the angle of reflection
Longitudinal wave In a longitudinal wave the particles move along the line of the direction of travel of energy.
Normal a line at 90掳 to the surface at the point of incidence, (from which all angles are measured.)
Period. (T) 聽Time for one wave to pass a point or time for one wave to be produced. (s)
Principle of reversibility of light The principle of reversibility of light states that a ray of light which travels along any particular path from some point A to another point B travels by the same path when going from B to A.
Reflection when a wave “bounces off” a surface we say it is reflected. (Particles can also reflect)
Refraction when light waves travel from one material to another the waves slow down and there is a reduction in wavelength in the optical thicker material. Unless the waves enter along the normal there is also a change of direction.
Speed, (v) rate of covering a distance. Number of metres travelled per second. (ms-1) The speed of the waves is represented by the formula
Total Internal Reflection When a wave hits a boundary at an angle larger than the critial angle the wave is entirely reflected if the material on the other side of the boundary is less optically dense.
Transverse wave In a transverse wave the particles move at 90 degrees to the direction of the flow of energy.
Wave 聽a way of transferring energy.
Wave speed the speed at which the wave travels
Wavelength the distance between the same point on successive waves.
Wavelength, (位) 聽the distance between two successive points on a wave. (metre or m)
Wavelength, (位) The wavelength of a wave is the horizontal distance between two adjacent troughs or crests or any two corresponding points on the wave
