A)Rectilinear propagation of light B) Pure substances c)Circuit

pls tell me

Answer 1

Answer:

A) Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. When light travels through a medium, say air or water, it follows a straight line. However, the path only changes in case there is a shift in the medium.

B) Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. Pure substances are further classified as elements and compounds. An element is a substance that consists of only one type or kind of atom.

C) A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. Water flows over a cliff as a light snowfall returns evaporated water to Earth.
