Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators. In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna. The oscillating electrons in the antenna generate oscillating electric and magnetic fields that radiate away from the antenna as ra… WebThe UV lamp in our lab is fixed in the cell culture hood (Ushio germicidal bulb, UVC, wavelength 253.7 nm, 15 watt, 55 volt) and I need to introduce 5J/m2 to my cells.

WebWhen a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant. If the beam of light is not orthogonal (or rather normal) to the boundary, the change in wavelength results in a change in the direction of the beam. WebThe visible spectrum is composed of light with wavelengths ranging from approximately 400 nanometers to 700 nanometers.
