How wide is this order spectrum on the wall

Reference no: EM13547216

Visible light (wavelength 400 - 700 nm) passes through a diffraction grating with 5000 lines/cm and illuminates a wall 5.0 m away. What is the highest order spectrum that can be seen in its entirety (all wavelengths are visible)? How wide (linear distance) is this order spectrum on the wall?
