How does light travels in a straight line only?
Answers
Answer:
Fermat's Principle says that light takes the shortest path (in terms of time taken) from one point to any other. The shortest path is a straight line in empty space but a curved one where gravity is significant or where the medium is not uniform.
Llight in free space moves in straight lines with constant velocity wrt inertial reference frames. It does not move in straight lines or with constant velocity in accelerating reference frames or in non homogeneous media
Answer:
light do not travel in a straight line.
Light is neither a wave nor a particle.
According to the wave theory light is considered as a wave but the corpuscular theory states that it is a particle.
Their is a part called as diffraction in light where the light has the ability to bend and move in a straight line
Explanation:
demonstration
off all the lights in your room and stand there with your friend ask him or her to hold a torch light u can see your shadow and hence you can understand that light is a wave and do not travel in straight line if it travels in straight line you can't see the shape of your shadow
