Explain about the monochromaticity of laser.
Monochromaticity:
The light emitted through a laser is monochromatic, that is this is of one wavelength (colour). Although in case of ordinary light, several wavelengths of light are emitted. It is the properties of laser, which differentiate this from ordinary light.
Induction: The property of magnetism may be induced in a piece of material that does not normally have that characteristic. If a piece of soft iron is placed in the magnetic
