MCQ

The true statement is

A
The order of colours in the primary and the secondary rainbows is the same
B
The intensity of colours in the primary and the secondary rainbows is the same
C
The intensity of light in the primary rainbow is greater and the order of colours is the same than the secondary rainbow
✓
The intensity of light for different colours in primary rainbow is greater and the order of colours is reverse than the secondary rainbow

✓

Answer

Correct option: D.

The intensity of light for different colours in primary rainbow is greater and the order of colours is reverse than the secondary rainbow

d
Primary rainbow is formed because of one total internal reflection and two refraction of white light by water droplet. A secondary rainbow appears outside of a primary rainbow and develops when light entering a raindrop undergoes two internal reflections.

Answer: The true statement is the intensity of light for different colour in primary rainbow is greater and the order of colour is reverse than the secondary rainbow.

A copper ball of radius $1\, cm$ and work function $4.47\,eV$ is irradiated with ultraviolet radiation of wavelength $2500\mathop A\limits^o $. The effect of irradiation results in the emission of electrons from the ball. Further the ball will acquire charge and due to this there will be a finite value of the potential on the ball. The charge acquired by the ball is
