[@colorsoflove7204]

If the small particles in the atmosphere can only scatter light of shorter wavelength, then why the sky is blue but not violet? Violet should have been scattered the most.

[@adzcreativity8660]

Good question. It depends on the intensity of sunlight... if you observe the graph, the intensity of component colors of white light rises gradually from Violet and is the most at Yellow... then decreases again till Red. It is a parabola (VIBGYOR) Hence, the intensity of Blue light is way more then the intensity of violet light in a ray of white light. Hope it helped.

Thanks

[@shikhashakya5065]

Sir why we cannot see near object less 25cm

[@adzcreativity8660]

Because at 25 cm, our ciliary muscles contract a lot. So to view objects placed nearer than 25 cm, our ciliary muscles have to contract to great extent.. hence our eyes struggle to focus clearly
