Refraction Flashcards
What is the definition of refraction
The change of speed of a wave as it moves from one material to another
What is the speed of light in air
3×10 (8) m/s
What is the speed of light in glass
2x10(8) m/s
What happens to the speed and wavelength when light refracts
The speed and wavelength change
What happens to the frequency when light refracts
The frequency remains constant
The more dense the material the more…
The more it refracts light
Is the angle in the air always larger than the angle in glass
Yes
What happens when white light is refracted by a triangular prism
The white light splits into the continuous visible spectrum
What colour of the visible spectrum has the longest wavelength
Red
What colour of the visible spectrum has the shortest wavelength
Violet
does ultraviolet have a longer wavelength than infrared
no
