(a) What is the minimum angular spread of a 633-nm wavelength He-Ne laser beam that is originally 1.00 mm in diameter? (b) If this laser is aimed at a mountain cliff 15.0 km away, how big will the illuminated spot be? (c) How big a spot would be illuminated on the Moon, neglecting atmospheric effects? (This might be done to hit a corner reflector to measure the round-trip time and, hence, distance.) Explicitly show how you follow the steps in Problem-Solving Strategies for Wave Optics.
(a) The dwarf planet Pluto and its moon, Charon, are separated by 19,600 km. Neglecting atmospheric effects, should the 5.08-m-diameter Palomar Mountain telescope be able to resolve these bodies when they are 4.50109 km from Earth? Assume an average wavelength of 550 nm. (b) In actuality, it is just barely possible to discern that Pluto and Charon are separate bodies using a ground-based telescope. What are the reasons for this?
Radio telescopes are telescopes used for the detection of radio emission from space. Because radio waves have much longer wavelengths than visible light, the diameter of a radio telescope must be very large to provide good resolution. For example, the radio telescope in Penticton, BC in Canada, has a diameter of 26 m and can be operated at frequencies as high as 6.6 GHz. (a) What is the wavelength corresponding to this frequency? (b) What is the angular separation of two radio sources that can be resolved by this telescope? (c) Compare the telescope’s resolution with the angular size of the moon.

JUST NEED HELP WITH D-J! A large container holds two layers of liquid: a 10.0 cm thick layer of vegetable oil (ρ = 920 kg/m3 , n = 1.47) above a 20.0 cm thick layer of water (ρ = 1000 kg/m3 , n = 1.33). There is air (ρ = 1.20 kg/m3 , n = 1.0003) above the oil layer. Nia holds a red laser which emits 632.8 nm light to the right and down, so that the ray makes an angle of 50.0° relative to a line normal to the oil layer. a) Draw a diagram showing the layers of liquid and the path of a light ray. At each interface between media, there should be a reflected ray and a refracted ray unless there is total internal reflection at that interface (in which case write N/A for the angle of refraction). Label the angles of each ray (incident, reflected, and refracted) for each interface. b) What is the angle of reflection at the air→ oil interface? ________________________ c) What is the angle of refraction at the air→ oil interface? ________________________ d) What is the angle of incidence at the…
