optics

The study of light is called

• optics

• acoustics

• mechanics

• thermodynamics

The image formed in a plane mirror is

• real image

• virtual image

• real and virtual

The angle between the surface and the incident ray is

• angle of incidence

• angle of reflection

• angle of deviation

• glancing angle

• Glancing angle

• angle of incidence

• angle of reflection

• angle of deviation

formula for the angle of deviation is ............

• d = 180 -2i

• d = 180 + 2i

• d = 90 - 2i

• d = 90 + 2i

formula for finding the number of images formed by two inclined mirrors when the object is at symmetrical distance

The angle between the normal and the reflected ray is

• angle of incidence

• angle of reflection

• glancing angle

• angle of deviation

The image in the mirror is

• real

• virtual

• real and virtual

magnification of a plane mirror is equal to

• • +1

• -1

• +2

• -2

formula for finding the distance between two reflections is
