Read the following paragraph and answer any four questions from 17(i) to 17(v)
The rays of light are traveling towards the focal point on the way to the lens. Because of the negative focal length, the light rays will head towards the focal point on the opposite side of the lens. These rays will actually reach the lens before they reach the focal point. These rays of light will refract when they enter the lens and refract when they leave the lens. As the light rays enter into the more denser lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.
(i) The above paragraph is about
(a) converging lens
(b) diverging lens
(c) plane glass
(d) spherical mirrors
