Question

the velocity of light in air 3 into 10 to the power 8 metre per second -1 what is the velocity of light in a medium was refractive index is 1.8​

Answer 1

Answer:

16X10^7 m/s

Explanation:

as we know changed vel. = vel./refractive index

so new vel. = 3X10^8 m/s / 1.8

= 16X10^7 m/s

Answer 2

Answer:

glad to know that same here

inst a gram I'd?
