A

Perpendicular

2
Q

In a longitudinal wave the oscillations are ………. To the direction of energy transfer

A

Parallel

3
Q

What type of waves show areas of compression and rarefaction

A

Longitudinal

4
Q

What type of waves are electromagnetic waves

A

Transverse

5
Q

What type of waves are sound waves

A

Longitudinal

6
Q

What type of waves are mechanical waves

A

They may be either transverse or longitudinal

7
Q

What do waves transfer

A

Waves transfer energy and information without transferring matter

8
Q

Waves can be …., ….. and ….

A

Waves can be reflected, refracted and diffracted

9
Q

Reflection

A

The change in direction of a light ray or a wave at a boundary when the ray or wave stays in the incident medium

10
Q

Refraction

A

The change in direction of a light ray when it passes across a boundary between two transparent substances (including air)

11
Q

Diffraction

A

The spreading of waves when they pass through a gap or around the edges of an obstacle which has a similar size as the wavelength of the waves

12
Q

What must be the case of appreciable diffraction to take place

A

For appreciable diffraction to take place, the wavelength of the wave must be of the same order of magnitude as the size of the obstacle or gap
