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?
Answer to relevant QuestionsYellow- green light of wavelength 550 nm in air is incident on the surface of a flat piece of crown glass at an angle of 40o. (a) What is the angle of refraction of the light? (b) What is the speed of the light in the ...For total internal reflection to occur inside an optic fiber as shown in Fig. 22.29, the angle u must be greater than the critical angle for the fiber–air interface. At the end of the fiber, the incident light undergoes a ...The angle of incidence and angle of refraction along a particular interface between two media are 30o and 40o, respectively. What is the critical angle for the same interface? A beam of light is incident on a plane mirror at an angle of incidence of 35o. If the mirror rotates through a small angle of θ, through what angle will the reflected ray rotate? (a) If you look into a shiny spoon, you see an upright image on one side and an inverted image on the other (Fig. 23.24). (Try it.) Why? (b) Could you see upright images on both sides? Explain.
