Question:

When a low flying aircraft passes over head, we sometimes notice a slight shaking of the picture on our $TV$ screen. This is due to

  • diffraction of the signal received from the antenna
  • interference of the direct signal received by the antenna with the weak signal reflected by the passing aircraft
  • change of magnetic flux occuring due to the passage of aircraft
  • vibration created by the passage of aircraft

The Correct Option is C

Solution and Explanation

When a low flying aircraft passing overhead, then it causes a change in magnetic flux and thus, causes a disturbance in picture on our $TV$ screen.

Waves

Waves are a disturbance through which the energy travels from one point to another. Most acquainted are surface waves that tour on the water, but sound, mild, and the movement of subatomic particles all exhibit wavelike properties. inside the most effective waves, the disturbance oscillates periodically (see periodic movement) with a set frequency and wavelength.

Types of Waves:

Transverse Waves -

Waves in which the medium moves at right angles to the direction of the wave.

Examples of transverse waves:

  • Water waves (ripples of gravity waves, not sound through water)
  • Light waves
  • S-wave earthquake waves
  • Stringed instruments
  • Torsion wave

The high point of a transverse wave is a crest. The low part is a trough.

Longitudinal Wave -

A longitudinal wave has the movement of the particles in the medium in the same dimension as the direction of movement of the wave.

Examples of longitudinal waves:

  • Sound waves
  • P-type earthquake waves
  • Compression wave
