What image is one where light rays appear to reflect of it ?

An object placed in front of a convex lensOf focal length 10cm produces an image at a distance of 15cm From the lensAnd on the same side as the object.Determine the position of the object

find wave velocity when in shm when y=0.25cos (125t- 0.25x)

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.

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?

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?
