How does light reflect through a periscope
WebReflection of light. Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular … WebAny object in the line of sight reflects the light making it visible in the periscope.

WebSep 12, 2024 · Figure 1.5. 1: (a) A ray of light crosses a boundary where the index of refraction decreases. That is, n 2 < n 1. The ray bends away from the perpendicular. (b) The critical angle θ c is the angle of incidence for which the angle of refraction is 90°. (c) Total internal reflection occurs when the incident angle is greater than the critical ... WebFrom now on we can conclude that a periscope is an instrument that uses a system of prisms, lenses or mirrors to reflect images through a cylindrical tube. Light from a distant object hits the upper mirror and is then reflected at a 90-degree angle through the cylindrical tube of the periscope.
WebReflection of light occurs when light hits a smooth surface that does not absorb any of the light but instead bounces it back off the surface.
