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.

Arcseconds are the smallest units for measuring angular distance and also provide the most precise measurement. Therefore your angular distances should always be converted into arcseconds unless noted otherwise. The moon is measured as being 3' 40" away from the planet it orbits. Convert this distance into arcseconds (Remember that 1' = 60") This is the same as dealing with time and asking how many total seconds pass after 3 minutes and 40 seconds. a. 210-214 b. 215-218 c. 219-221 d. 222-226
