- A nearly perfect paraboloidal mirror has a residual RMS surface error of /40, where A is the wavelength of light. The mirror focuses light from a distant star on axis. What is the resulting wavefront error after the reflection from the mirror if one neglects the effect of atmospheric seeing? Find Strehl ratio for the mirror and the amount of energy concentrated in the central maximum of the star image.arrow_forwardAstronauts 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.arrow_forwardNo glass is perfectly transparent. Mainly because of reflections, about 92% of light passes through an average sheet of clear windowpane. The 8% loss is not noticed through a single sheet, but through several sheets, the loss is apparent. How much light is transmitted by a double-paned window (one with two sheets of glass)?arrow_forward
- 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?arrow_forwardBuilding contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. In the figure, a double-glazed window consists of two identical panes of glass (ng = 1.54), each yg = 22.0 mm thick, separated by an air gap of y₁ = 17.6 mm. Use na = 1.00 for the index of refraction of air. If light incident on the glass makes an angle of d = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room. Ax = glass air glass mmarrow_forwardYou shine a monochromatic red light of frequency 4.30 x 10^14 Hz into a flint glass.

- A sound wave with a frequency of 15.1 kHz emerges through a circular opening that has a diameter of 0.193 m. Find the diffraction angle e when the sound travels (a) in air and (b) in water.

Inside the box at one end is a small radio transmitter that emits radiation with a wavelength of 0.120 m. A receiver is placed at the other end, 7.20 m away. Assume both the transmitter and the receiver are on the floor of the box. The walls and floor of the box interior are treated to minimize reflection of radio waves. The ceiling of the box interior, however, is metal, so the radio waves can reflect off of it almost perfectly. The radio waves can take two paths from the transmitter to the receiver: a straight-line path, and a path that reflects off the ceiling of the box interior. Note that there is a phase shift when the waves reflect off the ceiling. (a) What is the minimum (nonzero) height of the box ceiling (in m) that could produce destructive interference between the direct and reflected waves at the receiver's location? (b) What If? Some modern Wi-Fi antennas emit frequencies in the 5 GHz band.…arrow_forwardYou may have noticed that the eyes of cats appear to glow green in low light. This effect is due to the reflection of light by the tapetum lucidum, a highly reflective membrane just behind the retina of the eye. Light that has passed through the retina without hitting photoreceptors is reflected back to the retina, thus enabling the animal to see much better than humans in low light. Suppose the eye of a cat is 1.34 cm in diameter. Assume that the light enters the eye traveling parallel to the principal axis of the lens. If some of the light reflected off the tapetum lucidum escapes being absorbed by the retina, what is the horizontal distance ?from the retina to the point where the light will be focused? Neglect any effects due to the liquid in the eye. x = ? cm The refractive index of the liquid in the eye is about 1.4. How does this affect the location of the image relative to where it would be if the eye were filled with air?arrow_forward

A single oscillator makes the speakers vibrate in phase at a frequency of 1.98 kHz. At what angles, measured from the perpendicular bisector of the line joining the speakers, would a distant observer hear maximum sound intensity? Minimum sound intensity? (Take the speed of sound to be 340 m/s. Enter the magnitude of the angle only.)maximum intensities: (List smallest magnitude angle first.)?1max = ?2max = ?3max = minimum intensities: (List smallest magnitude angle first.)?1min = ?2min =arrow_forwardAssume the indices of refraction for air, water, and glass are 1.00, 1.33, and 1.50, respectively. When illuminated from above, a ray reflected from the air-water interface undergoes a phase shift of φ 1 = π, and a ray reflected at the water-glass interface also undergoes a phase shift of π. Thus, the two rays are unshifted in phase relative to each other due to reflection. For constructive interference, the path difference 2t must equal an integer number (m) of wavelengths in water. a. Derive the equation in terms of λ based on the situation above. b. If this m-value is an integer the wavelength undergoes constructive interference upon reflection in terms of λ, compute for the wavelengths for the following thickness: t= 2 x 10 5 m at m 700 nm and m 400 nmarrow_forward
