Two waves are represented in usual notation as y1 = a1 sin (ωt) and y2 = a2 sin(ωt). Their intensities are I1 and I2. What would be the ratio of their amplitude?
The noise from an airplane engine 25.0 m from an observer is found to have an intensity of 45.0 dB. What will be the intensity in decibel when the plane flies overhead at an altitude of 2.0 Km?
The intensity level from a loudspeaker is 100 dB at a distance of 10 m. What is its intensity level at a distance of 100 m?
The intensity level from a loudspeaker is 100 bB at a distance of 10 m. What is its intensity level at a distance of 200 m?
When a jet plane is flying at an elevation of 1000 m the sound level on the ground is 4.0 dB. What would be the intensity level on the ground when its elevation is as low as 50 m?
When a jet plane is flying on elevation of 1000m the sound level on the ground 4.0 db. What would be the intensity level on the ground when its elevation is as low as 100m?
Is there a physical difference between the intensity and intensity level of wave? How are these quantities related?
