Waves

Question 1

Longitudinal Waves

Answer 1

Sound waves and a stretched spring are longitudinal. P waves (fast moving longitudinal seismic waves) are also longitudinal waves. In longitudinal waves the direction of vibration is the same as the direction of travel.

Question 2

Transverse Waves

Answer 2

Light and other types of electromagnetic radiation are transverse waves. In transverse waves the vibrations are at a right angle to the direction of travel

Question 3

Electromagnetic Spectrum ( shortest to longest )

Answer 3

Gamma, X-ray, Ultraviolet, Visible light, Infra red, microwaves, radio waves

Question 4

Name three different behaviour of waves

Answer 4

Diffraction
Reflection
Refraction

Question 5

what is the amplitude

Answer 5

The height of the wave above midpoint

Question 6

what is the frequency symbol F measured in

Answer 6

Hertz Hz

Question 7

The wave equation

Answer 7

wave speed equals frequency times wavelength

V = f lamda

Question 8

Refractive Index

Answer 8

refractive index equals speed of light in a vacuum / speed of light in the medium
