During laser vision correction, a brief burst of 193-nm ultraviolet light is projected onto the cornea of a patient. It makes a spot 0.80 mm in diameter and evaporates a layer of cornea 0.30 µm thick. Calculate the energy absorbed, assuming the corneal tissue has the same properties as water; it is initially at 34ºC. Assume the evaporated tissue leaves at a temperature of 100ºC.

The movable mirror of a Michelson interferometer is attached to one end of a thin metal rod of length 23.3 mm. The other end of the rod is anchored so it does not move. As the temperature of the rod changes from 15°C to 25 C , a change of 14 fringes is observed. The light source is a He Ne laser, =632.8 nm . What is the change in length of the metal bar, and what is its thermal expansion coefficient?
An electric current through hydrogen gas produces several distinct wavelengths of visible light. What are the wavelengths of the hydrogen spectrum, if they form first-order maxima at angles 24.2°, 25.7°, 29.1°, and 41.0° when projected on a diffraction grating having 10,000 lines per centimeter?
During laser vision correction, a brief burst of 193 nmultraviolet light is projected onto the cornea of the patient. Itmakes a spot 1.00 mm in diameter and deposits 0.500 mJ of energy.

In a large vacuum chamber, monochromatic laserlight passes through a narrow slit in a thin aluminum plate and formsa diffraction pattern on a screen that is 0.500m from the slit. When thealuminum plate has a temperature of 20.0C, the width of the centralmaximum in the diffraction pattern is 2.75 mm. What is the change inthe width of the central maximum when the temperature of the plate israised to 520.0C? Does the width of the central diffraction maximumincrease or decrease when the temperature is increased?

A beam of light with wavelength 440 nm in air hits a thin piece of glass 10.28 microns thick (with refractive index 1.55) at an angle of 40.8 degrees to the normal. What is the path difference between the two reflections from the layers of the glass, in wavelengths? [Note to get the phase shift we multiply this number by 2π, but this is modulo 2π, i.e. any integer number of wavelengths are 2π phase shifts, equivalent to no phase shift... basically in terms of phase we only really need the non-integer part of your answer. Note also that for the phase shift we would need to add a π for the reflection off the glass-air interface.]
A bubble is formed by a soap film with index of refraction n=1.3 and a thickness of 325nm. When illuminated by white light and viewed directly (perpendicular to the surface), what wavelength in the visible spectrum (375nm to 725nm) will be strongly reflected?
Monochromatic laser light flows through a small slit in a thin aluminum plate and generates a diffraction pattern on a screen 0.620 m from the slit in a huge vacuum chamber. When the aluminum plate is heated to 20.0C, the width of the diffraction pattern's center maximum is 2.75 mm. When the temperature of the plate is increased to 520.0C, what is the change in the breadth of the center maximum? When the temperature is raised, does the breadth of the center diffraction maximum rise or decrease?
