Question

give one point of diffrence between a prism, lens and a plane mirror.

Answer 1

prism show dispersion phenomena
lens may be converging or diverging in nature
plane mirror is laterally inverted and show image of same size as that of object

Answer 2

Diffrence between a prism, lens and a plane mirror,are as follows -

• The prism causes dispersion of the light rays which means it divides the white light into seven basic colours of VIBGYOR spectrum range.

• The lens (both diverging and converging) causes refraction of the light rays which falls upon one surface of the lens.

• The plane mirror causes regular reflection of the light rays which falls upon the reflective surface of the plane mirror.
