DIFFRACTION OF WAVES

DIFFRACTION OF WAVES

1. MEANING :-

   • A phenomenon in which waves spread out as they pass through a gap or round a small obstacle.

2. CHARACTERISTICS :-

   • Frequency, wavelength and speed of waves DO NOT CHANGE.
   • Changes in the direction of propagation and the pattern of the waves.

3. FACTORS THAT INFLUENCE THE EFFECT OF DIFFRACTION

   • The effect of diffraction is obvious if the shape of the diffracted waves more spread out or more circular.
     • 1. the size of the gap/obstacle (is small enough)
     • 2. the wavelength (is large enough)
