what is the law of reflection?
the law of reflection is that the angle of incidence of the same as the angle of reflection
1 of 7
what is diffraction?
the waves travel along until they teach a gap. The width of the gap is similar to the waves wavelength.
2 of 7
what is the formula to find frequency?
time=1divided by frequency or frequency = 1 divided by time
3 of 7
how do you find the wave speed?
wave speed = frequency X wave length
