The diffraction phenomenon can be observed whenever the wavelength is comparable in magnitude to the size of the slit opening. To be “diffracted,” how fast must a person weighing 84 kg move through a door 1 m wide?

A beam splitter is an optical device that splits a beam of light - half of the incident light is transmitted through the beam splitter, and half is reflected.  Supposed we could make a beam splitter that reflects only 35% and transmits the other 65% (rather than 50/50). A beam of laser light with wavelength 656 nm is incident on our imaginary 35/65 beam splitter, at an angle of 45°. The beam pulse lasts 1.50 ms, and has a diameter of 0.60 mm. The intensity of the transmitted beam is 3.25 kW/m2.  Draw a clear physics diagram of the problem. What is the energy of a photon from this laser?  Find the peak Electric field of the reflected beam.  Find the peak Magnetic field of the incident beam.     What color is the laser beam?   What momentum is transferred to the beam splitter by the laser pulse?

The pupil of an eagle’s eye has a diameter of 6.0 mm. Two field mice are separated by 0.010 m. From a distance of 202 m, the eagle sees them as one unresolved object and dives toward them at a speed of 15 m/s. Assume that the eagle’s eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects?

Electromagnetic wave of unknown wavelength passes through the slit of width a =3.79 µm and the first minimum is detected at angular position 0 =6.82°. What is the wavelength of the electromagnetic wave? Provide your answer in nanometers, round it to one decimal place.

Given the aperture function Ax) f(x) = tri(x – a) + tri(x + a) where – |x], if |x| < 1 0, elsewhere tri(x) Determine its diffraction pattern as Fourier transform. You can use Fourier tables as needed.

In a diffraction experiment the 1st order light (m = 1) from a diffraction grating  is falling onto a single slit (see picture below). The light from the slit is then observed on a second screen and the measured width of the central diffraction peak is found to be 8 mm. Calculate the number of lines per millimetres of the grating. The distance from the slit to the second screen is 1.37 m, the distance from the diffraction grating to the screen with the slit is 5 m, the slit width is 0.25 mm and the distance from the middle of the screen with the slit to the slit is 10 mm..

An X-ray beam of wavelength 2.3 × 10-10 m makes an angle of 35° with a set of planes in a crystal which results in first order constructive interference.  Determine the plane spacing in nanometers. (Please include 2 decimal places).

An X-ray beam of wavelength 8.9 × 10-10 m makes an angle of 29° with a set of planes in a crystal which results in first order constructive interference.  Determine the plane spacing in nanometers. (Please include 2 decimal places).

Monochromatic light of wavelength 475 nm from a distant source passes through a slit that is 0.0300 mm wide. In the resulting diffraction pattern, the intensity at the center of the central maximum (θ = 0∘) is 9.60×10−5 W/m^2 . What is the intensity at a point on the screen that corresponds to θ = 1.20∘.
