Concept explainers

Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Mamenchisaurus, a sauropod dinosaur from Sichuan province in the Late Jurassic period, has one of the longest recorded necks of any species on Earth, ranging from 9 – 14 metres in length. Early reconstructions of sauropods placed them underwater like hippopotamus, with their heads protruding from the water like long breathing tubes or snorkels. Assuming that the dinosaur is underwater in a lake or other body of fresh water, as shown in the image; and the distance from the dinosaur's nose to its lungs is 13.7 metres, determine the (outside) pressure on the lungs. (Units: Pa). For the dinosaur to be able to breathe in (draw air into its lungs), its body must have had the capacity to reduce this pressure on the lungs, to the point where the pressure inside was less than the pressure at the dinosaur's nose
