The angle of incidence is found to be twice the angle of refraction when ray of light passes from vacuum into a medium of refractive index ' '. The angle of incidence will be
Options
- A⁻¹ ( 2 )
- B2 ⁻¹ ( 2 )
- C⁻¹ ( 2 )
- D2 ⁻¹ ( 2 )
Correct answer
B. 2 ⁻¹ ( 2 )
Step-by-step solution
Snell's law, = i r Given: i =2 r aligned r & = i 2 & = i ( i 2 ) & = 2 ( i 2 ) ( i 2 ) ( i 2 ) & =2 ( i 2 ) aligned i=2 ⁻¹ ( 2 )
