please help I will rate!! Q. The critical angle for total internal reflection at aliquid-air interface is 42.5degrees a. If a ray of light traveling in the liquid has an angle ofincidence of 35 degrees at the interface, what angle does therefracted ray in the air make with the normal? b. If a ray of light traveling in air has an angle ofincidence of 35 degrees at the interface, what angle does therefracted ray in the liquid make with the normal? thanks again! please help I will rate!!

Explanation / Answer

Applying Snells law we have as, n1sini=n2sinr 1.33sin35=1*sinr r=49.716 1*sin35=1.33sinr r=25.548 Hence we get by it.
