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.
