Question

Light from a laser pointer or a sodium vapour lamp do not split on refraction. Give reason​

Answer 1

Refraction

Explanation:

Light can travel through various mediums like air, glass, water and oil. Generally, when light passes from one medium to a different, it bends at the surface separating the 2.

The bending of sunshine when light travels from one medium to a different is named refraction of sunshine.

The bent image of a spoon or a straw dipped during a liquid is thanks to refraction of sunshine. The image produced by a hand glass is additionally thanks to refraction.

When the sunshine from these sources bend sharply thanks to refraction, the colored lights they're made from get separated.

However, lights like the red light of a laser pointer or the traffic light of a sodium vapor lamp are single-colored lights. They are doing not split on refraction.
