How do light rays travel
WebAsk the students if they can see the light rays now (they should be able to, as the chalk dust creates a visible pattern). Ask them if light rays travel in curves or straight lines. (Answer: Light rays travel in straight lines.) We just discovered that light rays travel in straight lines. We can use this fact to construct a simple camera. WebRays of light travel from the object, through the pinhole and project an image on the screen at the back of the camera. As the rays pass through the pinhole they cross meaning an upside down image forms on the screen. How is a pinhole camera similar to the eye?

WebRed light has a longer wavelength than violet light. The refractive index for red light in glass is slightly different than for violet light. Violet light slows down even more than red light, so it is refracted at a slightly greater …
WebBlurt. vijanti dhanji answered. When a ray of light travels from one medium to another, it is bent and so travels in a new direction. The light is said to have been refracted, and the bending of light is called refraction. Refraction occurs when light travels from one medium to another and takes place at the boundary of the two media. WebDec 15, 2024 · Although light normally travels in straight lines, you can make it bend round corners by shooting it down thin glass or plastic pipes called fiber-optic cables. Reflection and refraction are at work inside these "light pipes" to make rays of light follow an unusual path they wouldn't normally take. Diffraction
WebIn this video segment adapted from Shedding Light on Science, light is described as made up of packets of energy called photons that move from the source of light in a stream at a very fast speed.
