A laser light was shone through a diffraction grating whose lines were 1/1000 mm apart. The distance was measured between the center spot and the first side spot andfound to be 99 mm. The distance from the diffraction grating to the first side spot was found to be 154 mm. Calculate the wavelength of light in nm that the laserpointer was emitting.
A diffraction grating with an unknown number of lines per mm, is illuminated by light at a wavelength l = 633 mm, and the first order diffraction pattern is seen at an angle β= 45.OO. Light of a second wavelength is shone on to the grating, whose second order diffraction pattern is seen at l = 62.00. What is the wavelength of the second beam?
2. A diffraction grating has 300 lines per mm. The grating is used to observe normally incident light with a wavelength of 440 nm. The grating is placed 1.3 m from a screen. Where on the screen will the first order bright line appear?
A 480 lines/mm diffraction grating is illuminated by light of wavelength 510 nm . How many bright fringes are seen on a 4.0-m-wide screen located 2.1 m behind the grating?
If the scientist uses a diffraction grating with 500 lines per mm and laser with a wavelength of 680 nm, what angle will a line from the grating to the second order bright spot make with the line from the grating to the central bright spot?
Light with wavelength = 410nm passes through a diffraction grating that has 1000 lines per mm. What is the diffracted angle for a first order (m=1) beam? Show your work. For question 2, if the screen is 5.00cm from the slits, what is the lateral distance between the oth and 1st order bright spot on the screen? Show your work.
