Question
The refraction through a spherical lens is different from the refraction through a glass slab in which of the following ways?
- The emergent ray is not parallel to the incident ray
- The light ray does not bend on passing through the optical center
- The refraction through a spherical lens forms an image of the object
- All of these
Hint:
The light ray passed through the spherical lens show deviation from that of the glass slab in
i) forming parallel incident and emergent rays,
ii) passing straight through the optical center without bending, and
iii) forming an image of the object.
The correct answer is: All of these
The refraction through a spherical lens is different from the refraction through a glass slab in all of the above-mentioned ways.
- The emergent ray is not parallel to the incident ray in the refraction through a spherical lens while the emergent and incident rays are parallel to each other in the refraction through a glass slab.
- In the case of the spherical lens, light ray does not bend on passing through the optical center
- In the case of the spherical lens, when the light ray refracts through a lens, it forms an image of the object.
