An x-ray photon is scattered from a free electron (mass m) at rest. The wavelength of the scattered photon is λ′, and the final speed of the struck electron is v.

a. What was the initial wavelength λ of the photon? Express your answer in terms of λ′, v, m, and the appropriate constants. For the wavelength of the scattered photon λ′ use the notation λf. (Hint: Use the relativistic expression for the electron kinetic energy.)
b. Through what angle ϕ is the photon scattered? Express your answer in terms of λ′, λ, m, and the appropriate constants. For the wavelength of the scattered photon λ′ use the notation λf.
c. Evaluate your result in part A for a wavelength of 5.50×10−3nm for the scattered photon and a final electron speed of 1.80×10^8m/s.
d. Evaluate your result in part B for a wavelength of 5.50×10−3nm for the scattered photon and a final electron speed of v. Give ϕ in degrees.

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
