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.

ASSIGNMENT INSTRUCTIONS FROM THE SQA

The first thing that you must do before starting your Assignment is to know what you will be doing, what expectations there are and how you will be writing this up. All of this is contained in the candidate guide below.

In another post ASSIGNMENT PRACTICAL EXPERIMENTAL SHEETS have been uploaded.

I think the following experiments would be suitable-

check that:

  1. the theory is in the compendium,
  2. the topic is in the course,
  3. there is a graph of your experiment online or in one of the text books in school. Does your graph contain data ie, are there proper points on the graph or is it a trendline- which do you think is better?
  4. there is theory that you can write about that relates to your experiment.

Remember If you’ve used the results from your experiment to determine further values, you should show at least one sample calculation.

Here is the what you can take into the write-up phase. Collect a polypocket and keep it all in there.

NOTE: TO ALL TEACHERS,  IT IS  YOUR RESPONSIBILITY TO CHECK THE SHEETS YOU ARE GIVING TO STUDENTS DO NOT BREACH THE STRICT GUIDELINES GIVEN IN THE ASSESSMENT GUIDE AND THAT THESE EXPERIMENT SHEETS MEET THE SPECIFICATIONS. YOU ARE ALSO RESPONSIBLE FOR CHECKING YOUR OWN RISK ASSESSMENTS, ITEMS IN THESE SHEETS ARE A GUIDE. 

I have updated the sheets for the 2023 session,

The ones with the mrsphysics logo have been updated.

This table has more than one page!
