Question 1
1 / -0

What is the change in intensity level when the intensity of a sound increases by a factor of 10⁵?

A
50 dB

B
60 dB

C
70 dB

D
80 dB

Solution

I/I_o= 10⁵
The increase in intensity level is given by:
L = 10 log₁₀(I/I_o) = 10 log₁₀(10⁵)
= 10 × 5 = 50 dB

A
π

B
π/2

C
2π

D
4π

Solution

The linear distance between two successive crests is equal to one wavelength. The phase difference corresponding to two successive crests is equal to 2π radians.
