Question # 1
Why can red light be used in a photographic dark room when developing films,but a blue or white light can not?
- Ans 1: As we known red light has longest wavelength in visible spectrum,therefore it has less energy than that of blue or white light.So red light is least scattered on account of its large wavelength.Hence photographic films and the materials concerned are less affected in the presence of red light than high energy blue of white light.
