Electromagnetic spectrum Edexcel

What do waves transfer?

• money

• energy

• matter

• current

What is the amplitude

• length of the wave

• depth of the wave

• height of the wave

• refraction of the wave

This is how long it takes for a wave to pass

• amplitude

• wavelength

• period

• velocity

What are the two types of wave?

• sound

• transverse

• light

• longitudinal

• EM waves

Oscillations travel at right angles in these waves

• transverse

• longitudinal

• sound waves

• popcorn

Oscillations are parallel to the direction of travel

• transverse

• longitudinal

• light

• EM waves

How is wave speed calculated?

• speed= frequency x wavelength

• speed= Hz x m

• speed= distance/ time

• speed= distance x time

How can we measure waves of water?

• Count the number of waves in a gap

• Count how many waves are in a given time scale

• Time how long it takes for 10 waves to travel 8m

• Ask your teacher

• Time how long it takes for a wave to get from one point of a known distance to another

What is refraction?

• The bouncing of light off of a shiny surface

• The bending of waves passing through a gap

• The bending of light when passing through different media

• Th making of light

What does TAGAGA mean?

• Towards the normal from air to glass

• Away from the normal from glass to air

• Towards the normal from glass to air

• Away from normal from air to glass
