Question 1
A beam of light traveling in air has an angle of incidence of 41.0º when it enters a medium which has an index of refraction of 1.51.
What is the angle of refraction of the beam inside the medium?
25.8
30.0
64.2
60.0
omit
Question 2
If the wavelength of the beam of light in air is 562 nm, then what is its wavelength while traveling through the medium?
849 nm
521 nm
354 nm
372 nm
omit
Question 3
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?
105.2º
66.8º
113.2º
74.8º
omit
Question 4
Referencing the following image, the angle labeled
q
3
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 69.0º
it reflects back into the medium at an angle of 48.5º
it escapes out of the medium at an angle of 41.5º
it escapes out of the medium at an angle of 27.5º
