Question 1

What is the equation for wave speed?

Answer 1

V = f Y
Wave speed = frequency x Wavelength

Question 2

What a longitudinal wave?

Answer 2

A wave where the oscillations are parallel to the direction that the wave is travelling.

Question 3

What is a transverse wave?

Answer 3

A wave where the oscillations are perpendicular to the direction that the wave is transmitting energy

Question 4

What is mechanical wave movement?

Answer 4

These waves require a medium to travel through, and transfer energy.
Wave mediums include:
-gases
-liquids
-solids

Question 5

What is electromagnetic wave movement?

Answer 5

These waves can travel through a vacuum because no medium is required to transfer the waves energy

Question 6

What are sound waves categorised as?

Answer 6

Sound waves are longitudinal waves which are mechanical in movement

Question 7

What is reflection?

Answer 7

When light bounces off a surface and onto another surface before into the eye.

Question 8

What is refraction?

Answer 8

When a light enters a new medium of a differing density which cause the light to bend

Question 9

What do sound waves travel in?

Answer 9

Compressions
