A white ray is incident obliquely on a glass slab with the first refraction. Which of the following will also occur?
A. Deviation
B. Dispersion
C. Reflection
D. All of these
Answered Feb 05, 2023
Option : A. Deviation
Correct Answer - C Velocity of light is different for different mediums. On entering the glass slab, the constituents colours of white light undergo different amount of deviation. Thus there is...
Correct Answer - C::D According to law of reflection `hatr= hate -2(hate.hatn)hatn "Here" hate= (hati + hatj -hatk)/(sqrt(3)), hatn =pmhati` so `hate.hatn = (1)/(sqrt(3)) implies hatr = (hati + hatj -...
Correct Answer - `14.8 kV`
Correct Answer - `15^(@)`
Correct Answer - `mu gt (1)/(sin 72^(@))`
Correct Answer - `cot A lt (sqrt(3)-1)` where A is angle of the prism.
Correct Answer - `d = t sin i[1-(cosi)/(sqrt(mu^(2)-sin^(2)i))]`
Correct Answer - (i) `57^(@)` (ii) `33^(@)` (iii) `40.5 ^(@)`
Correct Answer - `57.3^(@),32.7^(@)`
Correct Answer - `mu gt sqrt(2)`
