A thin sheet of transparent material is surrounded by air. The sheet has an index of refraction of 1.47, and is illuminated by monochromatic light of wavelength 554 nm.
(a) Calculate the wavelength of the light in the material.
nm
(b) Using this information, calculate the minimum thickness of the sheet, other than zero, for which there will be minimum reflection.
(c) Calculate the minimum thickness of the sheet for which there will be maximum reflection.
A string with a mass of 31 g and a length of 2 m is stretched under a tension of 67 N. How much power must be supplied to the string to generate a traveling wave that has a frequency of 51 Hz and an amplitude of 4 cm?
