Question

I)which one is Denser either water or diamond and why?
ii) which of the above media is rarer ?why?
iii)what does light do when it passes from glass to water ? why?
iv) why do light slows down when it passes from Ice to Diamond ?​

Answer 1

Answer:

i) Diamond is denser because the speed of light is less in Diamond and the speed of light is inversely proportional to density.

ii)Ice is the rarer than any other because Speed of light is more in it.

iii)The speed of light increases due to the decrease in density and the ray of light i.e. the incident ray bend away from the normal.

iv)Due to increase in density, the light slows down because the speed of light is inversely proportional to density.

Answer 2

1) Diamond is denser than water

2) Ice is rarer

3) the speed of light increases due to the decrease in and the ray of light

4) Due to increase in density the light slows down
