The rainbow is seen sometimes in the sky when it is raining. When one sees a rainbow, one?? back is towards the Sun. Internal reflection from water droplet causes dispersion. The final ray is in the backward direction.
A normal human eye can clearly see all the objects beyond a certain minimum distance. The human eye has the capacity to suitably adjust the focal length of its lens to a certain extent.

If the radius of earth shrinks by one percent and its mass remaining the same, then acceleration due to gravity on the earth?s surface will
The dimension of the modulus of rigidity, is
Resonance is a special case of forced vibration in which the natural frequency of vibration of the body is the same as the impressed frequency and the amplitude of forced vibration, is maximum. The amplitude of forced vibrations of a body increases with an increase in the frequency of the externally impressed periodic force.
