WebThe radio signal spreads out from the transmitter along the surface of the Earth. Instead of just travelling in a straight line the radio signals tend to follow the curvature of the Earth. This is because currents are induced in the surface of the earth and this action slows down the wave-front in this region, causing the wave-front of the ... WebA straight line is 'In the eye of the beholder'. As far as light is concerned it travels in a straight line from point A to point B. However, for a distant observer the trajectory may be a bit curved. The reason is that the geometry of space is a bit warped near a massive gravitational source like a black hole or even the sun.

Web1. Light travels in a straight line between any two points in space.This is the foundation of linear perspective: the behavior of light can be described through traditional Euclidean geometry.. When light encounters the … WebOct 10, 2024 · Academic Physics NCERT Class 7. According to the Photon theory of light, light consists of small particles called "Photons". These photons are particles that have momentum like normal particles. So these photons travel in straight lines unless there is an external force that acts on them.

WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in … WebSep 6, 2024 · In a vacuum, light will always travel in a straight line. That’s because it doesn’t encounter any resistance in a vacuum. There’s nothing for it to bump into and change direction. Of course, we don’t live in a vacuum so light does encounter resistance when it travels through things like air or water. But even then, it usually manages to ... WebLight can travel through empty space. Unlike sound, which needs a medium (like air or water) to travel through, light can travel in the vacuum of space.
