# The angles used in Snell’s law are always

Question

The angles used in Snell’s law are always

A Right angles

B measured between the ray of light and the normal line

C obtuse angles

D measured between the ray of light and the tangent line

The higher the index of refraction the

A More expensive the material

B Less we know about the material

C The less dense the material

D The more dense the material

Snell’s law helps us to determine

A How much time light spends in a material

B The angle by which light bends when entering a different material

C The speed of light in a vacuum with standard temperature and pressure

D Spherical aberration of a telescope.

If one measures the index of refraction to be 1.1, this material would be

A More dense than vacuum

B More dense than acrylic

C More dense than water

D Less dense than air

The higher density a material the

A Faster the speed of light

B Slower the speed of light

C Speed of light stays the same

D Speed of light cannot be determined
