4. A magnified, inverted image is located a distance of 32.0 cm from a concave mirror
with a focal length of 12.0 cm. Determine the object distance and tell whether the
image is real or virtual.

2. A diverging mirror with a focal length of 25 cm has a magnification of 0.50. How far
apart are the object and the image?

An object of height 7cm is placed a distance 25 cm in front of a thin converging lens
of focal length 35 cm. What is the height, location, and nature of the image? Suppose
that the object is moved to a new location a distance 90 cm in front of the lens. What
now is the height, location, and nature of the image?

1. A flower is placed 30 cm in front of a converging lens of focal length 20 cm.
Calculate the magnification of the image.
2. A diverging mirror with a focal length of 25 cm has a magnification of 0.50. How far
apart are the object and the image?
3. Determine the image distance and image height for 5.0 cm tall object placed 45.0 cm
from a concave mirror having a focal length of 15.0 cm.
4. A magnified, inverted image is located a distance of 32.0 cm from a concave mirror
with a focal length of 12.0 cm. Determine the object distance and tell whether the
image is real or virtual.
5. A focal point is located 20.0 cm from a convex mirror. An object is placed 12 cm
from the mirror. Determine the image distance

Measurements are made of the intensity distribution within the central bright fringe in a Young's interference pattern. At a particular value of y, it is found that I/Imax= 0.810 when 600-nm light is used. What wavelength of light should be used to reduce the relative intensity at the same location to 64.0% of the maximum untensity?

3.A laser beam is incident on two slits with a separation of 0.200 mm, and a screen is placed 5.00 m from the slits. An interference pattern appears on the screen. If the angle from the center fringe to the first bright fringe to the side is 0.181 degrees, what is the wavelength of the laser light?

Light enters a diamond, reflects internally several times, and then refracts back into air. What is the critical angle for diamond, given the speed of light in diamond is 1.24x108 m/s ?

Unpolarized light is sent through a linear polarizer. The intensity leaving the polarizer is 12.0 candelas. A second polarizer is placed after the first at an angle of 45.0°. What is the intensity after the second polarizer?
