QJEEM22Ph792e: JEE Main 2022 Physics - Class 12 JEEM22Ph792e Solution: In free space, an electromagnetic wave of 3 GHz frequency…

In free space, an electromagnetic wave of 3 GHz frequency strikes over the edge of an object of size λ100, where λ is the wavelength of the wave in free space. The phenomenon, which happens there will be :

Multiple Choice Options

  • A Reflection
  • B Refraction
  • C Diffraction
  • D Scattering

Step-by-Step Verified Solution

aλ=1100

For reflection size of obstacle must be much larger than wavelength, for diffraction size should be order of wavelength.

Since the object is of size λ100\frac{\lambda}{100} , much smaller than wavelength, so scattering will occur.
