Refraction Flashcards
what is refraction
is the bending of waves when they change speed
what is the normal
90 degrees to the surface
what is light rays
travels in straight lines
what is the medium
glass, air, water etc.
what is the law of reflection
the angle of incidence= the angle of reflection
what does the refraction do to the medium
it changes the direction as they enter they enter a different medium, this is caused by the change in speed of the waves it also causes the wavelngth to change
what happens when the light ray travels from more dense medium to a less dense medium
the light refracts away from the normal
what happens when a light ray enters a dense area
the light ray slows down
what happens when the light ray travels from less dense medium to a more dense medium
the light ray refracts towards the normal
