In a spectrometer experiment, monochromatic light is incident normally on a diffraction grating having 4.5xx10^5 lines per metre. The seond order line is seen at an angle of 30^@ to the normal. What is the wavelength of the light?

A beam of monochromatic light of wavelength lambda falls normally on a diffraction grating of line spacing d. If theta is the angle between the second-order diffracted beam and the direction of the incident light, what is the value of sin theta ?
