Reflection

Question 1

What is regular/specular reflection and name some example

Answer 1

occurs on smooth surfaces when parallel rays incident on teh surface are reflected from teh surface as parallel rays (water /mirror/ glass/shine marble)

Question 2

What is teh incident ray

Answer 2

ray of light approaching surface

Question 3

what is the refelctive ray

Answer 3

ray of light leaving mirror

Question 4

what is difuse reflection

Answer 4

parallel incoming rays are scattered by a rough or not flat surface

Question 5

What is the law of reflection

Answer 5

angle of incidence = angle of refelction (when measured against optical normal)

Question 6

Explain teh law of reflection

Answer 6

when a person looks into a flat mirror tehy see rays of light that are first reflected off them onto teh mirror which then reflects back into eyes
ray travels at a straight line (rule of light)
the light refletcs back at the same angle they hit at (law of reflection

Answer 7

upright, same size as object, laterally inverted, virtual, appears to be located as far inside mirror as the object, is infront
