Question

Ryan while verifying the laws of reflection of sound measured the angle between the incident sound waves and reflected sound wave to be 130 degree . What is the angle of incidence?

Answer 1

As we know, the angle of incidence = angel of reflection
And hence,

/ \
/ | \
/ | \

Now, angle on the either side of the middle line is 130°
Let angle of incident be x
And as, Angle of incidence = Angle of reflection,
2x = 130°
x = 130/2
x = 65°

Hence, Angle of incidence = 65°
Angle of reflection = 65°

Answer 2

angle of incidence is equal to angle of reflection 2 x is equal to 130 x is equal to 1 32 x is equal to 65
