Electromagnetic waves. Like water waves, electromagnetic radiation have the right to be characterized by a wavelength . Notification that the much shorter the wavelength, ll, the higher the frequency, ν. The wavelength in (b) is half as long as that in (a), and also the frequency of the wave in (b) is therefore twice as great as the frequency in (a).If tide (a) has actually a wavelength that 4.0 m and a frequency that 1.5×10^8 cycles/s, what room the wavelength of tide (b)?
λλ = 0.1 mmThe prefix mega- has actually the symbol M. Because M = 1×10^6M , 2450 MHz = 2.45×10^9 Hz. The wavelength that corresponds to 2.45×109 s−12.45×109 s^−1 top top the frequency axis that the number is around 1×10^−1 = 0.1 m.

You are watching: If the fourth shell (the n = 4 energy level) were shown, how many subshells would it contain?

Using the diagram, recognize whether the wavelength that the appliance"s radiation belongs to the visible an ar of the electromagnetic spectrum. Based upon your finding, would the appliance"s radiation be clearly shows to the human being eye?
NoFigure 1 reflects the visible an ar of the spectrum in the range of 10^−7 m, i m sorry is much shorter than the wavelength of this radiation, i beg your pardon is 0.1 m. The wavelength of the visible region range from 4×10^−7 m to 7×10^−7 m.
Photons that this radiation have actually less power than photons of visible light.From Planck"s equation, E=hv, and also v=c/λ, we check out that energy (E) and wavelength (λ) are inversely proportional. This means that the much longer the wavelength the the radiation, the less power the photons have, and vice versa. The wavelength of the radiation, 0.1 mm, is much longer than the wavelengths in the range of clearly shows light, for this reason its photons have actually less energy than that of visible light.

A Microwave OvenThe radiation has actually a wavelength the 0.1 mm , so that is in the microwaves an ar of the spectrum. Therefore, the appliance is most most likely a microwave oven
Does the wavelength of light increase or decrease together we proceed outward from the innermost band of the rainbow?
FalseThe frequency of radiation decreases together the wavelength increases because they room inversely related.
