Correct Answer: coherent and monochromatic
Solution : The correct option is coherent and monochromatic .
The term " laser", which stands for "Light Amplification by Stimulated Emission of Radiation", refers to the coherent (in-phase) radiation beam produced. When the radiated waves' amplitudes are summed in a coherent light source, a powerful radiation beam is produced. Typically, it only generates one or two wavelengths. Monochromatic radiation refers to a single wavelength.
