The correct answer is: B. Infra-red radiation.
Infrared radiation is a type of electromagnetic radiation that has a longer wavelength than visible light. It is invisible to the human eye, but it can be detected by cameras that are equipped with infrared sensors. Infrared radiation is often used in night photography and photography in mist and fog because it can penetrate through these conditions and allow the camera to capture images.
Ultraviolet radiation is a type of electromagnetic radiation that has a shorter wavelength than visible light. It is also invisible to the human eye, but it can be harmful to human skin and eyes. Ultraviolet radiation is not typically used in photography because it can damage camera sensors.
Microwave radiation is a type of electromagnetic radiation that has a wavelength that is longer than infrared radiation, but shorter than radio waves. Microwave radiation is used in a variety of applications, including cooking, radar, and telecommunications. Microwave radiation is not typically used in photography because it is not very effective at penetrating through materials.
Gamma radiation is a type of electromagnetic radiation that has a very short wavelength. It is the most energetic type of electromagnetic radiation and can be very harmful to human health. Gamma radiation is not typically used in photography because it is very difficult to control and can damage camera sensors.
