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 = 4 μm. The wavelength of the light in air is λair = 480 nm. Assume that the only difference between the two beams is caused by the air bubble.

Imagine that you have a Nikon microscope with the objective and eyepiece focal lengths of 0.29 cm and 3.00 cm, respectively. You are looking at the furry leg of an insect located at 0.30 cm from the objective lens. The near point of the person using the microscope is 25 cm and the far point is at infinity. What is the final overall magnification of the microscope?

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?

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
