Alight wave travels through glass (n = 1.50) at an angle of 35degrees. what angle does it have when it passes from the glass into water (n = 1.33)? use the equation .

a.40.3degrees
b.0.647degrees
c.0.509degrees
d.30.6degrees

Explanation :

It is given that the light waves travels through glass into water.

Refractive index of glass,

Refractive index of water,

Using Snell's law

Where is the angle when the light passes from the glass into water.

So, the correct option can be (A) " 40.3 degrees ".

compass can be used day and night, cloudy or sunny
