Some properties of light emitted by lasers include coherence (waves are in phase), directionality (highly focused beam), monochromaticity (single wavelength), and high intensity. These properties make lasers useful in a wide range of applications such as cutting, welding, communication, and medical procedures.
High energy density. Low dispersion.
Its transparent (see through).
A knowledge of physical sciences would be useful to a musician because they would have a better understanding of sound waves and sound properties. It would be useful to photographers so that they could understand light and the bending of light.

No. Part of the energy is wasted, mainly as heat.
Almost all elements have some properties which are useful and so they can be used for that purpose.
A light bulb emits light energy, which is useful for illuminating a space and providing visibility. Some light bulbs also produce heat energy, although this is often considered a byproduct rather than a primary source of useful energy.
A spectrometer is a device that is useful for viewing a spectrum of light. It allows for the measurement and analysis of different wavelengths of light within the spectrum, providing valuable information about the composition and properties of the light source.
