Dispersion occurs when different frequencies of light have different phase velocities, due either to material properties (material dispersion) or to the geometry of an optical waveguide (waveguide dispersion). A spectrometer (spectro-photometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light’s intensity but could also, for instance, be the polarization state.

By doing more work in less time we can increase the power. And, Power is inversely proportional to time taken to do a work. So, when we do more work in lesser time , power will also increase.

General purpose utility gloves are used for cleaning procedures such as handling soiled linens or decontaminating care areas. Utility gloves are more tear and puncture resistant than exam or sterile gloves.

Since, the the mass of the bullet is smaller than the mass of the rifle hence, the velocity of the bullet is more than the rifle recoil velocity. Also, kinetic energy is inversely proportional to the mass. Hence, when a bullet is fired from a rifle and the rifle recoils freely then the kinetic energy of the rifle will be less than that of bullet.
