sharp angle
Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.
diffraction
entering a different medium, changes the speed of the wave, therefore the direction changes accordingly, called refraction, for example light entering glass prism from air, bends towards its normal, 'choosing a shorter path out of the prism, think of it as ur suffering from ur physics assignment n looking for a shortcut, u r the wave, being slowed down by a different medium, o, poor thing, good luck for ur assignm=ent
The angle of incidence will equal the angle of refraction. If two medium have the same refractive index, light does not bend.
Waves may bend if they move from one medium to another.

Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
The angle of incidence will equal the angle of refraction. If two medium have the same refractive index, light does not bend.
The bending of a wave occurs when the wave hits a object?
Waves may bend if they move from one medium to another.
Since the angle of incidence is 0, there is no chance of refraction and so the angle of refraction too becomes 0.
when light rays enter a new medium in a new angle it may speed up or speed down
The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.
The particles compress and refract, passing along the energy. It travels faster in mediums with particles that are more tightly packed eg. moves faster in metal as opposed to wood. Also, the more dense the air, the faster sound waves travel.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.
