1.4 ANALYSING DIFFRACTION OF WAVES
a) Diffraction of water waves,
b) Diffraction of light waves,
c) Diffraction of sound waves.

Introduction :

1. Diffraction of waves ;

- “ Waves spread as they travel, and when they encounter obstacles or

slits they bend around it and pass into the region.”

1. Slits

i) Slit size≈ג

i) Slit size >ג

ii) The degree of diffraction is larger.

ii)The degree of diffraction is smalle
