What feature of the infrared waves make it useful for the haze photography?

Options

  1. ASince it has high frequency
  2. BSince it has large wave length
  3. CSince it is absorbed by the medium
  4. DSince it is invisible

Correct answer

B. Since it has large wave length

Step-by-step solution

Infrared waves have longer wavelengths compared to visible light waves. According to Rayleigh scattering, the intensity of scattered light is inversely proportional to the fourth power of the wavelength, expressed as I 1 ⁴ . Because infrared waves have larger wavelengths, they undergo significantly less scattering by atmospheric particles such as dust, smoke, and haze compared to visible light. This reduced scattering allows infrared radiation to penetrate through haze more effectively, making it useful for haze ph
