Q:

The attenuation in optical fibre is mainly due to

A) Scattering B) Absorption
C) Both (a) and (b) D) Neither absorption nor scattering
 
Answer & Explanation Answer: A) Scattering

Explanation:

The reason for transmitting data over optical fibers, is because the speed of data transmission through optical wires are equal to the speed of light. The intense speed of data transfer speed, has lead to the use of optical fibers. The optical fiber uses the technology of transferring light beams, from one end to the other end of optical cables. The attenuation in optical fiber is due to Scattering. The reason why scattering is caused, due to the folding, in the wire.

Q:

Which one of the following statements is not correct?

A) The response of the ear to sound of increasing intensity is approximately logarithmic. B) The sensitivity of the human ear does not vary with the frequency of the sound.
C) When two or more waves traverse the same medium, the displacement of any element of the medium is the algebraic sum of the displacements due to each wave. D) Longitudinal waves can travel in all media-solids, liquids and gases.
 
Answer & Explanation Answer: B) The sensitivity of the human ear does not vary with the frequency of the sound.

Explanation:

The human ear can respond to minute pressure variations inthe air if they are in the audible frequency range, roughly 20 Hz -20 kHz. In fact, tests conducted show an increased sensitivity in the 3000 Hz range which is the optimal amplification frequency in the human ear. So, the sensitivity of the human ear varies with the frequency of the sound.
