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!

This is a pdf of the power point that I a using

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=fλ 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 λ = 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 × wavelength

v=f λ

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.
