1what is the frequency of a wave?number of waves that pass a point per second
2list of the 7 electromagnetic waves from longest to shortest wavelengthRADIO
MICROWAVE
INFRARED
VISIBLE
UV
X-RAY
GAMMA
3which of the 7 magnetic waves have the longest/shortet wavelength and frequency?radio- longest=lowest frquency
gamma-shortest wavelenth=highest frequency
4what is the speed of electormagnetic waves?3x10 the power 8 m/s
5if a wave has a long wavelength what can we say about its frequency?frequency is low
6if a wavelength has a short wavelength it has a high frequency so what can we say about the energy it carries?high amount of energy
7is a higher or lower energy wave more dangerous?high
8what is the law of refraction?angle of incidence is equal to the angle of reflection
9what is refraction and why does it occur?refraction is the change in speed of a wave as it moves from one substance to another and it occurs becuase of a change of density between substances.
10when does a wave speed up/slow down?the wave speeds up if there is a decrease in density and bends away from the normal. however, it slows down if more dense and so bends towards the normal.
11what is diffraction?the spreading out of a wave as it passes through a gap
12when is diffraction at its maximum?when the size of the gap is equal to the wavelength
