Inwhich direction will the sun appear to set if the observe is inside the water of a pond? Refractive index of water , mu = 1.33. |
|
Answer» SOLUTION :For a setting sun the incident rays graze along the surface of water i.e. ANGLE of incidence = `90^(@)`. `therefore "According in Snell.s law",` `mu_(w) = (sini)/(sinr) or, 1.33 = (sin90^(@))/(sinr)` `or, "" sinr = (1)/(1.33) or, 1.33 = sin48.75^(@)` `therefore "" r = 48.75^(@)` Therefore, to see the setting sun the OBSERVE in water should LOOK at an angle of `48.75^(@)` with the normal. |
