P Diopter Change in Diving Cormorants Double crested cormorants (Phatacrocorax untus) are extraordinary birds - they can focus on objects in the air, just ke we can but ney can also focus underwater as they pursue their prey To do so, they have one of the argest accommodabon ranges in nature - that is, they can change the focal length of their yes by amounts that are greater than is possible in other animals. When a cormorant Aunges Into the ocean to calch a fish, it can change the refractive power bout 45 diopters, as compared to only 16 diopters of change passible in the human eye Should this change of 45 diopters be an increase or a decrease? ts eyes by Increase O decrease Previous AnswErs v Correct • Part B Explain. Sobm Previous Answers Submitted, grade pending • Part C If the focal length of the cormorant's eyes is 4.2 mm before it enters the water, what is the focal length alter the refractive power changes by 45 diopters?

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.
