Optics is the study of the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Resolving power of a prismThe spectral resolution of a spectrograph, or, more generally, of a frequency spectrum, is a measure of its ability to resolve features in the electromagnetic spectrum.

Spectrometer,Dispersive power of a prismSpectrometer is an instrument used to study the properties of light. In this experiment, spectrometer used to find the refractive index and dispersive power of prism

Diffraction GratingThis experiment involves diffraction of light waves though a very small slit (aperture), and demonstrate that when light passes through the slit, the physical size of the slit determines how the slit interacts with the light.
