Sample Refraction Exercises
On this worksheet you will examine several situations dealing with properties of the refraction of light.
A beam of light traveling in air has an angle of incidence of 25.0º when it enters a medium which has an index of refraction of 1.41.
What is the angle of refraction of the beam inside the medium?
If the wavelength of the beam of light in air is 562 nm, then what is its wavelength while traveling through the medium?
If part of the beam of light reflects off the surface of the medium, what is the angle between the refracted beam and the reflected beam?
Referencing the following image, the angle labeled
is the critical angle of the medium. Will the reflected ray shown also be internally reflected when it strikes the upcoming vertical interface or will it be refracted back out into the air?
it reflects back into the medium at an angle of 57.3º
it reflects back into the medium at an angle of 44.8º
it escapes out of the medium at an angle of 32.0º
it escapes out of the medium at an angle of 45.2º
What is the frequency of the light as it is traveling through the medium?
