Remote Sensing: Scattering, Rayleigh and other regimes Question: If the direct beam transmission of light of 0.5 micron wavelength is 80%, what will be the transmission of light with a wavelength of 1 micron, assuming no absorption is involved at either wavelength? Question: Sunlight shines through a salt shaker. Should you expect more, less, or the same amount of scattering from blue light compared to red light? How about for light shining through a plume of smoke? Question: A typical...

Biologists use optical tweezers to manipulate micron-sized objects using a beam of light. In this technique, a laser beam is focused to a very small-diameter spot. Because small particles are attracted to regions of high light intensity, the focused beam can be used to "grab" onto particles and manipulate them for various experiments. In one experiment, a 10 mW laser beam is focused to a spot that has a diameter of 0.82 μm. A) What is the intensity of the...
A transmission grating with d=150μm is illuminated at various angles of incidence by light of wavelength 600nm. Plot as a function of angle of incidence (0 to 90 degrees) the angular deviation of the first order diffracted beam from the incident direction.

A beam of ultraviolet light with wavelength of 280 nm is incident on a metal resulting in the ejection of photoelectrons. The photoelectrons leaving the metal have a minimum de Broglie wavelength of 0.88 nm. (a) Determine the work function of the metal and the stopping potential. (b) If a potential difference −0.5 V is applied to the metal with respect to the photoelectron detector, what is the de Broglie wavelength of photoelectrons collected at the detector?
A beam of unpolarised light with intensity I0 falls first upon a
polarizer with transmission axis ?TA,1, then upon a second
polarizer with transmission axis ?TA,2, where ?TA,2 – ?TA,1 = 90
degrees (in other words the two axes are perpendicular to one
another).

second polarizer? Show your working.
Now a third polarizer (Polarizer A in the figure below), whose
transmission axis is offset 45 degrees from...
