INSTANT ANSWER

A transparent cylinder of radius \( R=2.8 \) \( \mathrm{m} \) has a mirrored surface on its right half. A light ray traveling in air is incident on the left side of the cylinder. The incident light ray and exiting light ray are parallel and \( \mathrm{d}=1.9 \mathrm{~m} \). Determine the index of refraction of the material. state your answer to nearest 0.001 .

The index of refraction for violet light in silica flint glass is nv=1.68, and that for red is nR= 1.56. What is the angular dispersion of visible light passing through a prism of apex angle A= 57°, when the angle of incidence is 49°. ? State your answer to the nearest 0.001°

As a result of his observations, Roemer concluded that eclipses of lo by Jupiter were delayed by 25.6min during a 6 months period as the Earth moved from the point its orbit where it is closest to Jupiter to the diametrically opposite point where it is farthest from Jupiter. Using R= 152.5x10^6 km as the average radius of the Earth's orbit around the Sun, calculate the speed of light from these data. State your result in km/s to the nearest km/s
