Electromagnetic waves. Favor water waves, electromagnetic radiation deserve to be identified by a wavelength . An alert that the shorter the wavelength, ll, the greater the frequency, ν. The wavelength in (b) is half as lengthy as that in (a), and also the frequency the the tide in (b) is as such twice as an excellent as the frequency in (a).If tide (a) has actually a wavelength of 4.0 m and a frequency of 1.5×10^8 cycles/s, what space the wavelength of wave (b)?
λλ = 0.1 mmThe prefix mega- has the symbol M. Since M = 1×10^6M , 2450 MHz = 2.45×10^9 Hz. The wavelength that synchronizes to 2.45×109 s−12.45×109 s^−1 on the frequency axis of the figure 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 of the appliance\"s radiation belongs to the visible region of the electromagnetic spectrum. Based upon your finding, would certainly the appliance\"s radiation be visible to the human eye?
NoFigure 1 reflects the visible region of the spectrum in the variety of 10^−7 m, i m sorry is much shorter than the wavelength the 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 the this radiation have less power than photons of visible light.From Planck\"s equation, E=hv, and also v=c/λ, we view that power (E) and also wavelength (λ) are inversely proportional. This method that the longer the wavelength the the radiation, the less power the photons have, and also vice versa. The wavelength that the radiation, 0.1 mm, is longer than the wavelengths in the variety of visible light, therefore its photons have actually less power than that of clearly shows light.

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