Question

A straight line path along which light travels

Answer 1

HEYA MATE:-)

UR ANSWER:-

Light is a wave and although it spreads as it moves farther from its source, it can be approximated as a straight line. We can thus assume light as a ray, that is a straight path on which light moves in a homogeneous medium, the study of light (as a ray) is termed as ray optics.
