A microwave oven works by passing microwave radiation, usually at a frequency of 2450 MHz (a wavelength of 12.24 cm ), through the food.
Read moreWhat is the wavelength of a radiofrequency radiation that has a frequency of 2450 MHz?
a) 2450 MHz radiation has a frequency of 2450 million hertz (2450 x 106) or 2.450 x 109 Hz. This frequency corresponds with a wavelength of about 10-1 meters or 10 cm.
Read moreWhat is the wavelength of radiation in your microwave oven whose frequency is 2.45 GHz?
Following international conventions, microwave ovens at home or in restaurants operate at frequencies of about 2.45 GHz, i.e. λ = 12. 23 cm .
Read moreWhat is the wavelength of microwave oven waves?
The microwave region extends from 1,000 to 300,000 MHz (or 30 cm to 1 mm wavelength) . Although microwaves were first produced and studied in 1886 by Hertz, their practical application had to await the invention of suitable generators, such as the klystron and magnetron.
Read moreWhat wavelength of UV is harmful to humans?
The skin and eyes are most sensitive to damage by UV at 265–275 nm , which is in the lower UV‑C band. At still shorter wavelengths of UV, damage continues to happen, but the overt effects are not as great with so little penetrating the atmosphere.
Read moreIs UV long wavelength?
UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths . While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB.19 Ağu 2020
Read moreWhat are MM waves used for?
Millimeter-wave (mmW) frequencies (30–300 GHz) are being used for many applications in the modern world. These applications include,but not are limited to, radio astronomy, remote sensing, automotive radars, military applications, imaging, security screening, and telecommunications .
