is the amplitude the:
trough to the crest
from the rest position to the crest
what is one example of a transverse wave?
sound waves
shock waves
EM waves
In Transverse waves the vibrations are:
perpendicular to the direction of energy transfer
parallel to the direction of the wave
wave speed=
frequency times wavelength
wavelength divided by frequency
speed= frequency times wavelength which symbols are correct?
Hz times m
f times cm
All waves can be:
refracted,reflected and diffracted
refracted, spread out and bounced off
when waves arrive at an obstacle they:
spread out and diffract
refract
reflect
Angle of Incidence equals:
angle of reflection
angle of incidence
angle of diffraction
diffraction is:
waves changing speed
waves changing direction
waves spreading out
the waves with the highest frequency are:
radio waves
microwaves
gamma rays
Infared waves are used for:
photography
communication
remote controls and optical fibres
