For a person seeing an object placed in optically rarer medium
Apparent depth of the object is more than real depth
Apparent depth is smaller than the real depth
apparent depth might be smaller or greater depending on the position of the person
nothing can be concluded about the depth of object from given data
Refraction of light by the earth’s atmosphere due to variation in air density is called
atmospheric reflection
atmospheric dispersion
atmospheric scattering
atmospheric refraction
One cannot see through the fog, because
refractive index of the fog is very high
fog absorbs light
light is scattered by the droplets
light suffers total reflection at droplets
Which of the following phenomena contributes significantly to the reddish appearance of the sun at sunrise or sunset?
Dispersion of light
Scattering of light
Total internal reflection of light
Reflection of light from the earth
View Answer
At noon, the Sun appears white as
blue colour is scattered the most
red colour is scattered the most
light is least scattered
all the colours of the white light are scattered away
When white light enters a prism, it gets split into its constituent colours. This is due to
different refractive index for different wavelength of each colour
each colours has same velocity in the prism.
prism material have high density.
Scattering of light
When light passes at an angle to the normal from one medium into another in which its speed is higher
it is bent toward the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
