Physicsrefraction, reflection, diffraction and the wave equationGCSEAll boards Created by: live7Created on: 21-11-13 18:24 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 4 of 7 radio signals have longer wavelengths than television signals 5 of 7 waves are a series of oscillations or vibrations which travel through space. water waves make water molecules vibrate up and down sound waves make 6 of 7 sound waves make air particles vibrate from side to side. all waves transfer energy from one place to another 7 of 7
