化学,波长,能量 The wavelength of a beam of radio waves is 2.669x10^0 km. What is the energy (in J) of 2.62x10^-1 mole of its photons ?Note: Your answer is assumed to be reduced to the highest power possible.
What is the wavelength from a radio station having frequency 107.7 MHz? a) 2.790 m b) 27.90 m c) 32.30 m d) 323.0 m Radio waves: Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of th...

What is the wavelength of a radio wave having a frequency of 1.0 \cdot 10^8\text{ Hz} ? A laser emits 1 \times 10^{17} photons per second. What is the laser's emitted power? What is the wavelength range of cosmic rays?
1、Thewavelength, and hence the colour, of this light depends on the size of the dot.(光线的波长——即是对应着其颜色——取决于该微粒的尺寸。) 2、He went to a bar, in the bar, a shortwavelengthradio was broadcasting pop music.(酒吧里一台短波长的收音机正在播放流行音乐。) ...
prioritising those who did not have a radio or broadband access, and those who were living alone. The scheme, which ended in April 2020, showed an outpouring of concern and thoughtfulness from people who were nominating their grandparents, friends and neighbours to receive a vital radio set.”...
The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma rays. Conversely, radio waves have much longer wavelengths, reaching anywhere from 1 mm to 100 km, depending on the frequency. ...
(Science: radiobiology) The length of a single cycle of a wave, usually measured from crest-to-crest. For electromagnetic waves, the wavelength determines the type (radio, infrared, visible, ultraviolet,x-Ray, gamma-ray) ofradiation, in the case ofvisible light, wavelength determines the colour...
