A beam of coherent light of wavelength A0 623 nm in air is incident on a rectangular block of glass with index of refraction n 1.40. If, after emerging from the block, the wave that travels through the glass interfers destructively with the wave that travels through air. We ignore reflection on the block faces. Coherent...
When light hits a surface of a vacuum photocell with light of wavelength 555 nm electrons are barely ejected from the surface. You change the excitation wavelength to 401 nm. Calculate the ejected electrons kinetic energy and velocity. I would need the complete solution to understand the answer. Many thanks
A light beam of wavelength 550 nm is incident on a sheet of glass of index of refraction 1.3. Surrounding the glass is air (index of refraction about 1.0). If no reflected light is observed, what can one conclude is the thinnest the sheet of glass can be? Please explain the answer.

Name: 1.How much more energy per photon is there in green light of wavelength 532 nm than in red light of wavelength 635 nm? 2. When traveling through a translucent medium, such as glass, light travels more slowly than it travels through a vacuum. Red light with a wavelength of 684 nm travels through Pyrex glass with a frequency of 2.92 x 10 Hz. Calculate the speed of this light.
White light is incident on a block of glass that has index of refraction n = 1.816 for violet light and n = 1.800 for red light. The thickness of the block is L = 29 cm. If the angle of incidence is 30 degrees, what is the distance x between the violet and red rays when they emerge from the glass? Take the index of refraction of air to be 1.00.
