What do you study in optics?
Optics: : [op-tiks] – noun A branch of physics that studies electromagnetic radiation (for example, light and infrared radiation), its interactions with matter, and instruments used to gather information due to these interactions. Optics includes the study of sight.
What is optics and its types?
optics, science concerned with the genesis and propagation of light, the changes that it undergoes and produces, and other phenomena closely associated with it. There are two major branches of optics, physical and geometrical. Physical optics deals primarily with the nature and properties of light itself.
What are the branches of optics?
Classical optics is divided into two main branches: geometrical (or ray) optics and physical (or wave) optics. In geometrical optics, light is considered to travel in straight lines, while in physical optics, light is considered as an electromagnetic wave.
What is bouncing back of light called?
The correct option is A reflection. The bouncing back of light to the incident medium after hitting a shiny surface is called reflection of light.
What are the 3 types of optics?
Optics basics: The three major branches of optical science
- Geometrical optics, the study of light as rays.
- Physical optics, the study of light as waves.
- Quantum optics, the study of light as particles.

What is magnifying power of lens?
Magnifying power is how much larger a given lens can make an image appear. This is a direct relationship between the focal length of the lens and the least distance of distinct vision, or LDDV. The LDDV is the closest your eyes can comfortably look at an object.
What is V in lens?
v. = 1. f. where u is the distance of the object from the lens; v is the distance of the image from the lens and f is the focal length, i.e., the distance of the focus from the lens.
