Question

Find the angle of incidence​

Answer 1

Answer:

45°

Step-by-step explanation:

angle of incidence=90°-angle of reflection

                              =90°-45°

                              =45°

Answer 2

Answer:

Given:

→ Angle of reflection is 45°.

Find:

→ Find the angle of incidence for the given diagram.

Using formula:

★ ${\sf{\underline{\boxed{\red{\sf{Angle \: of \: incidence - Angle \: of \: reflection}}}}}}$

Calculations:

• Angle of incidence = 90°
• Angle of reflection = 45°

→ $\sf{Angle \: of \: incidence = 90° - 45°}$

→ ${\sf{\boxed{\boxed{\boxed{\pink{\sf{Angle \: of \: incidence = 45° }}}}}}}$
