Question

Speed of the Light wave__________ in any meadium.

Option
a) No Change

b) First Increases & then Decreases

c) Will Decreases(ધટશે)

d) Will Increases(વધી)​

Answer 1

Answer:

In most of the mediums refractive index n >1

so V=c/n is less than speed of light

speed of light decrease in going from rarer to denser medium (optically denser ,means with higher refractive index) ie from medium of low to medium of high refractive index and vice versa
