What feature of the infrared waves make it useful for the haze photography?
- A Since it has high frequency
- B Since it has large wave length
- C Since it is absorbed by the medium
- D Since it is invisible
Answer & Solution
Correct Answer
(B) Since it has large wave length
Step-by-step Solution
Detailed explanation
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 \(I \propto \dfrac{1}{\lambda^{4}}\). Because infrared waves…
