Question

.) The speed of propagation of a wave depends only upon the properties of the medium (stuff) that the wave is propagating through. If the amplitude (note: the power is proportional to the amplitude squared) of the wave is doubled then the speed of propagation of the signal through the medium will

            a.) increase

            b.) remain constant

            c.) decrease

            d.) vary randomly

The speed of propagation of a wave depends only upon the properties of the medium (stuff) that the wave is propagating through. If the frequency of the wave is doubled then the speed of propagation of the signal through the medium will

            a.) increase

            b.) remain constant

            c.) decrease

            d.) vary randomly

Explanation / Answer

As speed depends on medium properties.

amplitude is increases that will have no effect on speed.

ANS: (b) remains constant

v = f * wavelength

v will remain constant. if frequency is increased then only wavelength will decrease/

Ans: (b) remain constant
