In a Physics104 lab in UW-Madison, you are trying to find the wavelength of a monochromatic laser light by shining that to a pair of narrow slits, separated by 1.6  mm. You know that the light waves arrive at the two slits are in phase. If you set the screen 5.0 m from the slits you see a pattern formation with 5 complete bright fringes per centimeter on the screen near the center of the pattern. The wavelength of the light is closes to

An object is placed 9 cm to the left of a diverging lens (A) with a focal length of magnitude 8 cm (solid circles). This lens is 10 cm from a converging lens (B) with a focal length of magnitude 16 cm (open circles), as shown in the diagram. Where is the final image located?

An object is placed 12 cm in front of a converging lens with focal length 8 cm. What is the image distance and magnification of the image? How do we describe this image? (Note, you may want to draw a diagram)   dI       m            description

Which of the following statements are true about nearsighted vision? I. It is corrected with a diverging lensII. It is corrected with a converging lensIII. Uncorrected focused image is formed in the middle of the eye (in front of the retina) IV. Uncorrected focused image is formed behind the eye (past the retina)V. Distant objects can be seen clearly with no corrective lensVI. Image from just corrective lens (no eye) is closer than object

Unpolarized light travels through three polarizers, and the final intensity is 3/16 of the original intensity, as shown in the diagram. If the first polarizer is vertical, what is a possible orientation of the other two polarizers? (Angles in diagram are not indicative of solution.)   Polarizer 2:            Polarizer 3:   

In a Physics104 lab in UW-Madison, you are trying to find the wavelength of a monochromatic laser light by shining that to a pair of narrow slits, separated by 2.2 mm. You know that the light waves arrive at the two slits are in phase. If you set the screen 5.0 m from the slits you see a pattern formation with 6 complete bright fringes per centimeter on the screen near the center of the pattern. The wavelength of the light is closes to

You are sitting at an outdoor café facing a plane mirrored window. Your eyes are at a height of 1.5 m. The mirrored window extends to 3 m high off the ground. Where will you see an image of a bird flying directly above you at a height of 5 m above the ground when you look into the mirror?

Two coherent, monochromatic beams of light are traveling through water. One beam goes through an air bubble of width d. If the two beams are combined after the air bubble, what sort of interference would occur? Take nair = 1, nwater = 1.3, and d = 14 μm. The wavelength of the light in air is λair = 560 nm. Assume that the only difference between the two beams is caused by the air bubble.

Bernie is standing 40 cm in front of a concave mirror. If his image is 1.50  times as large as his face and erect, determine the mirror’s radius of curvature?

The World’s biggest radio telescope, the massive ALMA, is located in Chile and has a diameter of 12 m. What is the minimum angular separation, in degrees (˚), of the sources that can be resolved by this telescope in case the source emits a 25-cm wavelength wave? (Note that 1 radian=3.14=180˚)
