Sound waves undergo reflection and refraction, much as electromagnetic waves do. Here is one practical application of reflection and refraction in the field of health care: determining the location of a liver tumor. Suppose that a narrow beam of ultrasonic waves travels through surrounding tissue and enters the liver with an incidence angle of 51.0°. These inaudible sound waves travel 14.0% more slowly through the liver than through the medium that lies above. Suppose that the beam reflects off the tumor and emerges from the liver at a distance 13.0 cm from its entry point. Calculate the depth of the tumor (in cm) below the surface of the liver.

Astronauts placed a mirror on the surface of the Moon to be used for optical measurements of the precise distance to the moon. Visible light is sent from the Earth and is reflected back from the moon. If the mirror has a diameter of 30 cm, roughly how large is the beam of reflected light that reaches Earth? The distance from the Earth to the Moon is 3.8×108 meters. You can assume the light from Earth is a plane wave when it strikes the mirror.
high-frequency sound waves exhibit less diffraction than low-frequency sound waves do. However, even high frequency sound waves exhibit much more diffraction under normal circumstances than do light waves that pass through the same opening. The highest frequency that a healthy ear can typically hear is 2.0 × 104 Hz. Assume that a sound wave with this frequency travels at 344 m/s and passes through a doorway that has a width of 0.95 m. (a) Determine the angle that locates the first minimum to either side of the central maximum in the diffraction pattern for the sound. (b) Suppose that yellow light (wavelength = 567 nm, in vacuum) passes through a doorway and that the first dark fringe in its diffraction pattern is located at the angle determined in part (a). How wide would this hypothetical doorway have to be?

Very short pulses of high intensity laser beams are used to repair detached portions of the retina of the eye. The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 810 nm and delivers 250 mW of power spread over a circular spot 510 micrometers in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction of 1.34. (A) what average pressure would the pulse of the laser beam exert at normal incidence on a surface in air if the beam is fully absorbed? (B) what is the wavelength of the laser light inside the vitreous humor of the eye? (C) what is the frequency of the laser light inside the vitreous humor of the eye?

Hello, I am having trouble with my physics homework about the interference of light. I have enclosed a photo of the problem because it might be difficult to explain without it. It is asking me to find the wavelength of a green light in air, given the frequency of 5.435*10^14 Hz. The light travels through air, through a film of magnesium fluoride with an index of refraction of 1.38, and then into a piece of glass with an index of refraction of 1.55. Thank you!
