Geometric Optics + Spherical Reflection

Form of energy travels at speed of 2.99×10^8

Bouncing of Light from surface of object

When light strikes a non-smooth surface; reflected light scattered in all directions

If surface that light strikes is silvered + polished smooth then reflected as as single beam

Line/Vector perpendicular to a surface

Incident Ray, Normal at Incidence, Reflected Ray all lie on the same plane

Angle of Incidence = Angle of Reflection (i=r)

Image formed by the apparent intersection of Rays; can’t be formed on a screen

Image of right hand in a plane mirror is a left hand

Apparent movement of one object relative to another due to the motion of the observer. The object which is further away appears to move with the observer

Ray reflected back on the other side of the axis with refl ang = inc ang

Reflected back along its own path

Ray passes through focus after reflection

Ray comes out parallel to axis

Image formed by actual intersection of rays; can be formed on a screen.

Object’s outside focus, Image is inverted + in front of mirror

Object inside/at focus, Image upright/erect, magnified + behind mirror

Reflected at equal angle w axis

Reflected back along its own path

Reflected parallel to axis

Virtual, Upright, Diminished, Behind Mirror
