White light is incident onto a prism at the shown in Figure . Violet light emerges perpendicular to the rear face of the prism. The index of refraction of violet light in this glass is larger than the index of refraction of red light. At what does red light emerges from the rear face?
A microscope has a tube length. What focal-length objective will give total magnification localid="1649845070556" when used with an eyepiece having a focal length ?
A tall man is in front of a camera with a focal length lens. How tall is his image on the detector?
Alpha Centauri, the nearest star to our solar system is light years away. assume that alpha centauri has a planet with an advanced civilization. professor Dhg, at the planet's Astronomical Institute, wants to build a telescope with which he can find out whether any planets are orbiting our sun.
(a). What is the minimum diameter for an objectives lens that will just barely resolve Jupiter and the sun? The radius of Jupiter's orbit is Assume
(b). Building a telescope of the necessary size does not appear to be a major problem. What practical difficulties might prevent professor Dhg's experiment from succeeding?
A hydrogen discharge lamp emits light with two prominent wavelengths: (red) and (blue). The light enters
a flint-glass prism perpendicular to one face and then refracts
through the hypotenuse back into the air. The angle between
these two faces is .
a. Use Figure to estimate to the index of refraction
of flint glass at these two wavelengths.
b. What is the angle (in degrees) between the red and blue light
as it leaves the prism?
