When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it.

Infrared radiation is a part of the electromagnetic spectrum. Moreover, the spectrum includes other radiations from radio waves to X-rays. The radiation is characterized by wavelength. Thus, the x-rays, gamma, and ultraviolet are of short wavelength with high energy and quite dangerous. The infrared, radio waves and microwave are of longer wavelength and less harmful. Therefore, in this article, we are going to be discussing in detail this radiation in detail.

Reuven Silverman of Ophir discusses the critical role of M2 measurements in laser technology for optimization and quality control in various industries.

Answer 3: One of the most common examples of Infrared is the heat of the Sunlight. Interestingly even the heat produced from radiators, fireplace etc are also Infrared radiation. The most common aspect of Infrared radiation is that it raises the surface temperature of the body.

Answer 1: Radiation is generally famous for causing cellular damage. However, Infrared radiation is not potent enough to cause the development of malignancy. But, studies show that this radiation can reduce the efficiency of DNA  repair as a result of increased skin temperature. In some rare cases, there have been signs of discrepancy in the skin thickness which happens due to Infrared radiation exposure.

Midinfrared

Answer 2: No, both of them are entirely different. While red light is visible to naked eyes, Infrared light is not. We cannot feel the red light on the skin. However, since Infrared light generates heat, there will be a sensation of temperature rise on the skin when we expose it to Infrared.

British Astronomer, William Herschel first introduced this term to the board of Scientist in 1800 using a simple experiment with thermometer. As the thermometer was placed in the path of light, the colors of the spectrum showed temperature change.

The transmission of data through infrared rays is quite common in the communication of the short-range. We utilize the light-emitting diodes for emitting this radiation. Further, the focus is done on a narrow beam with the support of a plastic lens. At the end of the receiver, the photo-diode converts radiations into electric current.

Infrared radiations are also known as thermal or heat waves. The range of wavelength is between 710 mm to 1 mm. The rays also characterize as near and far-infrared rays. The near-infrared rays have use in photography and TV remote sensor.
