Waves

Question 1

What are waves?

Answer 1

Waves are a method to transfer energy, and are a moving disturbance/oscillation/vibration about a fixed point.

Question 2

What do waves not transfer?

Answer 2

They do not transfer the material

Question 3

What are longitudinal waves?

Answer 3

Waves in which the medium (material or matter) vibrates/oscillates in the same direction the wave travels in.

Question 4

What are transverse waves?

Answer 4

Waves in which the medium vibrates/oscillates perpendicular to the direction the wave travels in.

Question 5

What are some examples of a longitudinal wave?

Answer 5

Sound, P – seismic,
Pressure, Shock, slinky

Question 6

What are some examples of a transverse wave?

Answer 6

Light, Water, S – seismic, slinky, rope, Electromagnetic radiation (Radio, Micro, IR, visible light, UV, X, Gamma)

Question 7

What is the frequency?

Answer 7

The number of vibrations passing each second.

Question 8

What is the amplitude?

Answer 8

The size of the vibrations. Distance between the equilibrium position and the maximum displacement

Question 9

What is the wavelength?

Answer 9

Distance over which 1 complete
vibration/oscillation/wave cycle happens

Question 10

What is the wavespeed?

Answer 10

The speed that a wave propogates
