Does light from space objects exert pressure on the lenses of optical telescopes?
| September 21, 2020 | Education
Light undoubtedly exerts pressure on the lenses of reflector telescopes, and this pressure is twice the pressure exerted on a non-reflective surface.
Light will also exert pressure on the transparent objectives of refractor telescopes, since when light passes through a collecting lens, the component of photon impulses directed along the main optical axis decreases.
