Question

24.
The refractive index of a medium 'x' with respect to a medium y is 2/3
and the refractive index of medium y' with respect to medium 'Y' is 4/3.
Find the refractive index of medium z with respect to medium 'x. If the
speed of light in medium 'x' is 3* 10^8 ms^-1 calculate the speed of light
in medium 'y​

Answer 1

Answer:

BRO ANSWERS IS 9/8

Explanation:

SPEED IN Y / SPEED IN X =2/3

SPEED IN Y / 3×10^8 =2/3

SPEED IN Y = 3×10^8×2/3

SPED IN Y = 2×10^8 M/S

SPEED IN Z /SPEED IN Y = 4/3

SPEED IN Z /2×10^8 =4/3

SPEED IN Z =8/3×10^8

SPEED IN X/SPEED IN Z = 8/3×10^8

SPEED IN X / SPEED IN Z=REFRACTIVE INDEX

3×10^8 / 4/3 ×10^8 = REFRACTIVE INDEX

9/8 = REFRACTIVE INDEX
