Exam 11: Properties of Light

Light known to be polarized in the horizontal direction is incident on a polarizing sheet. It is observed that only 15 percent of the intensity of the incident light is transmitted through the sheet. What angle does the transmission axis of the sheet make with the horizontal?

The index of refraction of water is approximately 1.33. The angle of incidence for maximum polarization by reflection from water is approximately

The fact that light can be polarized shows that it must be

You place a point source of light at the bottom of a pool of water 1.00 m deep. The source emits rays upward in all directions. You notice that a circle of light is formed by the rays that are refracted into the air and that the rays outside of this circle are reflected back into the water. The index of refraction of water is 1.33. The radius R of the circle at the surface of the water is approximately

A ray of light in glass is incident on a glass-air interface as shown. You would expect the ray to pass through

Use the following figure for the next two problems. -The film shows the line spectrum of an unknown element. If the wavelengths of lines (a), (b) and (c) are 410 nm, 500 nm and 556 nm respectively, then the color of line (d) is

The index of refraction of a sample of glass cannot be determined by measuring the

The light ray that passes through the prism and emerges at the angle of minimum deviation for that ray is

Light from an underwater source at O impinges upon a water-air interface. The critical angle is

Light is an electromagnetic wave. When visible light is plane polarized,

One would not attempt to polarize light by

Plane-polarized light cannot be produced by

Light is incident on a piece of glass in air at an angle of 37.0º from the normal. If the index of refraction of the glass is 1.50, the angle that the refracted ray makes with the normal is approximately

You see a fish in water at an apparent depth of 1.83 m. The actual depth of the fish, if the index of refraction of the water relative to air is 4/3, must be

A light ray traveling in glass strikes a glass-water surface. At angles greater than $\theta$ _c the light ray is totally internally reflected. The value of $\theta$ _c is

An air prism is immersed in water. A ray of monochromatic light strikes one face as shown. The emerging ray is

A 60 $\degree$ prism has a refractive index of 1.64 for blue light and 1.61 for red light. Calculate the difference in the angle of emergence from the opposite face of the prism for a beam of red and a beam of blue light that are both incident at an angle of 60^o.

You shine light of frequency 4.00* 10¹⁴ Hz through a glass plate whose index of refraction for this light is 1.50. The wavelength of this light in the glass is approximately

The minimum angle of deviation produced by a glass prism (n = 1.70 for the light used) whose apex angle is 45º is approximately

Light is reflected from the surface of a lake (n = 1.33). What is the angle of incidence for which the reflected light is 100 percent polarized?
