Question:
If the speed of light in carbon disulphide and vacuum is X and Y, respectively, then
If the speed of light in carbon disulphide and vacuum is X and Y, respectively, then
Options:
- a) X < Y
- b) X > Y
- c) X >= Y
- d) X = Y
- a) X < Y
- b) X > Y
- c) X >= Y
- d) X = Y
correct answer : a)
Explanation:
Speed of light in vacuum (Y) is the highest and always more than that in any medium (like carbon disulphide, X). Hence, X < Y.
Speed of light in vacuum (Y) is the highest and always more than that in any medium (like carbon disulphide, X). Hence, X < Y.
