electromagnetic spectrum and waves

Question 1

what is the order of the electromagnetic spectrum?

Answer 1

radio, microwave, infrared radiation, visable, UV, X-ray and gamma

Question 2

what is a wave

Answer 2

disturbance that carries energy from place to place

Question 3

whats a electromagnetic wave

Answer 3

does not need a medium in order to move

Question 4

whats a mechanical wave

Answer 4

must have a medium in order to move

Question 5

whats a transverse wave

Answer 5

medium moves at right angles to the direction of the wave

Question 6

whats a longitudal wave

Answer 6

moves back and fourth in same direction the wave travels

Question 7

parts of longitudal wave

Answer 7

compression - particles are close together
rarefaction - particles are spread apart

Question 8

whats wavelength

Answer 8

distance between one point on a wave to the equivalent point on the adjacent wave

Question 9

wave equation:

Answer 9

yk this

Question 10

parts of transverse wave

Answer 10

crest, wavelength, amplitude, wave height, trough

Question 11

amplitude?

Answer 11

displacement of a point on the wave away from its undisturbed position

Question 12

crest and trough?

Answer 12

c = highest point on a wave t = lowest point on a wave

Question 13

waveheight?

Answer 13

vertical distance between the crest and its neighbouring trough
