Question

a) Which ray PO & ray OQ denote.
(b) What are ∠ and ∠ called?
(c) What will be the value of ∠ and ∠?
(d) How will you find the value of ∠ and ∠

Answer 1

Answer:

a) PO --> incident ray and OQ ----> reflected ray

b) ∠ PON ----> angle of incidence &

∠ NOQ ------> angle of reflation

c) the value of ∠ PON = 90° - ∠ AOP

and the value of ∠NOQ = 90° - ∠ BOQ

d)

∠AON - ∠ AOP = ∠ PON

AND

we know that

angle of incidence = angle of reflation

so ,

∠ PON = ∠NOQ
