Electromagnetic Waves

The carrier of electromagnetic interaction is photon

In the electromagnetic spectrum, the wavelengths increase in this order: Thus, for the given three: This means X-rays have the shortest wavelength, microwaves the longest.

Infrared (IR) waves are part of the electromagnetic spectrum, with wavelengths longer than visible light. The key feature of infrared waves that makes them useful for haze photography is their large wavelength. - Option A: Since it is invisible - This is incorrect. While infrared light is invisible to the human eye, the primary feature that makes infrared useful for haze photography is not its invisibility but its ability to penetrate through fog and haze due to its longer wavelength.
- Option B: Since it has large wavelength - This is the correct option. Infrared waves have longer wavelengths than visible light, which allows them to pass through haze, fog, and smoke more effectively than visible light. This makes them ideal for applications like haze photography, where the ability to see through such obstructions is necessary.
- Option C: Since it is absorbed by the medium - This is incorrect. Infrared waves are not significantly absorbed by the medium (like fog or haze); rather, their larger wavelength allows them to pass through such obstructions, unlike visible light, which is scattered more easily.
- Option D: Since it has high frequency - This is incorrect. Infrared waves actually have lower frequencies compared to visible light. The feature that makes them useful in haze photography is their longer wavelength, not high frequency.
Thus, the correct answer is Option (B): "Since it has large wavelength."
