A) When a light source is moving relative to an observer, the wavelengths of its spectral lines are shifted to longer or shorter wavelengths.
B) When the temperature of a light source is increased, the wavelength of maximum emission decreases.
C) When a light source is located in a magnetic field, the emitted spectral lines are split into two or more components.
D) When light is focused on a metal surface, electrons are ejected from the metal only if the wavelength of the light is shorter than some critical wavelength.
