- What would be the refractive index of a compound at 20 C, if its refractive index was at 22.9 C and 1.4730 ?A flat sheet of ice (n = 1.309) has a thickness of 2.1 cm. It is on top of a flat sheet of crystalline quartz (n = 1.544) that has a thickness of 1.2 cm. Light strikes the ice perpendicularly and travels through it and then through the quartz. In the time it takes the light to travel through the two sheets, how far (in cm) would it have traveled in a vacuum? Number i UnitsWhat would be the speed of light through a particular medium if the frequency is 5.63 x 106 Hz and the wavelength is 63.86 m? Your answer for this problem will not have any decimal places.
- Compute the index of refraction for the substance where lightpropagates with speed v = 2.1 × 10 8 m/s (speed of light in vacuum isc = 3 × 10 8 m/s) Calculate to 2 decimals.In 1676, the Danish astronomer Ole Roemer had one of those “aha” moments in science. He concluded from accumulated observations of eclipses of Jupiter’s moon at different times of the year that light must travel at finite speed and needed 1300 s to cross the diameter of Earth’s orbit around the Sun. Using 300,000,000 1cm for the diameter of Earth’s orbit, calculate the speed of light based on Roemer’s 1300-s estimate. How does it differ from a modern value for the speed of light?Lunar astronauts placed a reflector on the Moon’s surface, from which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. What percent error is this, given the average distance to the Moon is 3.84 × 108 m?
