waves

Question 1

give the order of the waves in the em spectrum

Answer 1

radiowaves
microwaves
infared 
ultraviolet
x rays
gamma

Question 2

what has the longest wavelength

Answer 2

radio

Question 3

highest wavespeed radio

Answer 3

radio

Question 4

highest frequenc

Answer 4

gamma

Question 5

what do all of the waves travel at

Answer 5

3 x 10^8

Question 6

waht is dispersion

Answer 6

when all of the colours of the spectrum spread out from visible light

Question 7

radio waves

Answer 7

long wavelength means that they can travel far into earths atmosphere

Question 8

microwaves

Answer 8

particles absorb the heat particles from the waves

Question 9

infared

Answer 9

infared detectectors everyone gives it out, so at night this can be deteted

Question 10

UV

Answer 10

chemicals which turn uv rays into visible light

Question 11

x rays

Answer 11

penetrate through some materials but can’t be absorbed by others.

Question 12

londitudinal

Answer 12

contain waves that are made up of rarefactions

rarefactions have low pressure due to being apart.

Question 13

transverse waves

Answer 13

vibrations move perpendicular to the direction of travel

Question 14

frequency

Answer 14

waves that pass a fixed point per second

Question 15

amplitude

Answer 15

distance from the top to the rest position

Question 16

uses of total internal reflection

Answer 16

fibre broadband sends computer information coded as pulses of light
