1. The variations in the observation of a dim star under different viewing conditions.

Introduction:

The human retina contains photoreceptors called rod and cone cells. These cells are responsible for dim and bright vision, respectively. They have the capability to absorb the light and then transform this light into electrical signals. The signals can cause a change in the potential of the membrane and lead to visual phototransduction.
