All waves transfer
Last week we looked at light reflected by a mirror. How big is the angle of reflection compared to the angle of incidence? Tick (
) one box.
What is the angle between the normal and the mirror? Tick () one box.
Light is what kind of wave?
Light travels fastest through...
Periscopes can be used to see over things.
The diagram shows a ray of light entering a periscope.
Complete the lines to show the path of light to the eye.
Add arrowheads on the lines to show the direction the rays are travelling.
Big challenge! (You can do it!!)
When light moves into a medium that has particles tighter together, it slows down and shifts towards the normal line. It does the opposite when moving into a substance where particles are more spread out. Show how it moves through each substance differently.
