Question: A grating with 7000 lines per centimeter is illuminated by a monochromatic light. Determine the wavelength of the light in nanometers if the second order

A grating with 7000 lines per centimeter is illuminated by a monochromatic light. Determine the wavelength of the light in nanometers if the second order maximum is at 608. Please give the answer with no decimal places. An X-ray beam of wavelength 4.8 x 10'10 m makes an angle of 26 with a set of planes in a crystal which results in rst order constructive interference. Determine the plane spacing in nanometers. (Please include 2 decimal places). Light of wavelength 584 nm illuminates a round 0.5-mm diameter hole. A screen is placed 7.2 m behind the slit. What is the diameter of the central bright area on the screen in millimeters? Give the answer with no decimal places please
