Question

different types of formulae for intensity of light ,sound etc​

Answer 1

Answer:

Explanation:

n physics, intensity is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m2).

FOR SOUND

hysics Tutorial - Sound - Decibel Levels

Find the ratio of the sound intensity to the threshold intensity.

Take the logarithm of the ratio.

Multiply the ratio by 10.

Divide the decibel level by 10.

Use that value as the exponent of the ratio.

Use that power of ten to find the intensity in Watts per square meter.
