Microphone converts ___________ energy into ____________ energy.

A microphone is connected to the Y-input of a C.R.O. Three different sounds are made in turn in front of the microphone. Their traces (a), (b) and (c) produced on the screen are shown in Fig. Which trace is due to the loudest sound ? Give reason for your answer.

A microphone is connected to the Y-input of a C.R.O. Three different sounds are made in turn in front of the microphone. Their traces (a), (b) and (c) produced on the screen are shown in Fig. Which trace is due to the sound with the lowest pitch ? Explain your answer.

A microphone is connected to a cathode ray oscilloscope. A loudspeaker giving a single note is switch on . The trace shown in the figure appears on the screen. Which of the following the softer but same frequency note of the given note ?

A microphone of cross sectional area 0.80 cm^2 is placed in front of a small speaker emitting 3.0 W of sound output. If the distance between the microphone and the speaker is 2.0 m how much energy falls on the microphone in 5.0 s?

According to law of conservation of energy. "Energy can neither be created nor be destroyed, but can be changed from one form to another form". The sound energy in a microphone changes into
