What is rectilinear propagation of light and what is the speed of light????
Answers
Answer:
The rectilinear propagation of light means that light travels in straight lines as a wave. ... In a pinhole camera, the light rays reflecting from the bottom of the object travel in a straight line through the pinhole to the film.
Answer:
I hope it will help you.
Explanation:
Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction. Light does not deviate when travelling through a homogenous medium, which has the same refractive index throughout.
2.The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second. Wikipedia
