Question
Consider the following statements and consider which are true and which are false.
A)White light that is reflected from some ordinary surface will be separated into a visible spectrum.
B)Total internal reflection is possible when light approaches (with sufficiently large angle of incidence) a boundary with a different medium that has a higher index of refraction.
C)Light travels faster in glass than it does in a vacuum.
D)When light enters a medium with a lower index of refraction, the ray is bent closer to the line normal to the boundary.
E)If one stands by a swimming pool, a person standing in the pool will seem to have short legs.
Explanation / Answer
A) False:
If white light that is reflected from some ordinary surface will does not split into its component colors. This is possible with prism, the splitting process is called dispersion.
( B ) False:
Total internal reflection is possible when light passing from denser medium to rarer medium. It means it should enter into a lower index of refraction medium.
( C ) False:
The speed of light is greater in vaccume, since vaccume refractive index is 1. Light travels slower in glass than it
does in a vacuum.
( D )False:
When light enters a medium with a lower index of refraction, the ray is bent away from the line normal to the boundary.
( E ) True
If one stands by a swimming pool, a person standing in the pool will seem to have short legs due to refraction of light
