Question: The critical angle for a certain type of glass in
The critical angle for a certain type of glass in air is 41.8o. What is the index of refraction of the glass?
Answer to relevant Questions(a) For total internal reflection to occur, should the light be directed from (1) air to water or (2) water to air? Explain. (b) What is the critical angle of water in air? Light passes from material A, which has an index of refraction of 4/3, into material B, which has an index of refraction of 5/4. (a) The speed of light in material A is (1) greater than, (2) the same as, (3) less than the ...To a submerged diver looking upward through the water, the altitude of the Sun (the angle between the Sun and the horizon) appears to be 45o. (a) The actual altitude of the Sun is (1) greater than, (2) the same as, (3) less ...A flint glass plate 3.5 cm thick is placed over a news-paper. How far beneath the top surface of the plate would the print appear to be if you were looking almost vertically downward through the plate? The index of refraction of crown glass is 1.515 for red light and 1.523 for blue light. (a) If light of both colors is incident on crown glass from air, the blue color will be refracted (1) more, (2) less, or (3) the same ...
