1

Define a wave

Waves are a transfer of information or energy without the transfer of the medium

2

Define longitudinal wave

A wave where vibrations are parallel to the direction of the wave

3

Define a transverse

Waves that are perpendicular to the direction of the wave

4

What is frequency ?

The number of waves per second passing a point

5

What is a wavelength ?

The horizontal distance between coherent points on adjacent waves

6

Define displacement

A straight line distance from the central line

7

What is time period ?

Time taken for one wave

8

Equation for speed of a wave

Speed of a wave = frequency x wave length

9

Equation 2 for speed of wave

speed of wave = distance / time

10

Define diffraction

When waves meet a gap in a barrier, they carry on through the gap. However, the waves spread out to some extent into the area beyond the gap.
