Laws Of Reflection |
-incident + reflected rays and normal all lie on the same plane at the point of incidence -angle of incidence = angle of reflection |
|
|
Characteristics of a PLANE MIRROR image |
-laterally inverted -upright -same size as object -virtual |
|
|
Speed of light in different optical mediums |
-optically denser medium → more difficult for light to pass through → light travels slower -optically less dense medium → easier for light to pass through → light travels faster |
|
|
Refraction Definition |
Bending effect of light as it passes from 1 transparent medium into another bc of a difference in optical density |
|
|
Total Internal Reflection Definition + Conditions |
-the complete reflection of a light ray inside an optically denser medium at its boundary with an optically less dense medium -a ray of light travels from an optically denser to less dense medium -the angle of incidence in the optically denser medium > critical angle |
|
|
Critical Angle Definition |
angle of incidence in an optically denser medium for which the angle of refraction in the optically less dense medium is 90° |
