Question

Find the velocity of light in a medium if critical ange is 45

Answer 1

Answer:

2.121x10^8

Step-by-step explanation:

n=1

sinC=1

Sin45=

$\sqrt{2}$

therefore,

speed of light in vaccum= speed of light/n

= 3x10^8/root2

= 3x10^8/1.414

Since, root 2 = 1.414. = 2.121x10^8

divide 3 by 1.414
