It is measured in terms of Hertz (Hz) or s-1. d. As the wavelength of a photon increases, its frequency decreases. Twice the frequency means one-half the wavelength. The distance travelled by a wave in a unit of time is equal to one wavelength. As can be seen in the diagram above, as wavelength decreases (the waves become closer together), frequency increases (more waves in the same time frame). As the wavelength of a photon increases, its energy decreases. 2. Analyze: Click Reset.

Experts are tested by Chegg as specialists in their subject area. The relationship between energy (E), frequency and wavelength can be described with this equation: If the frequency of a wave is doubled, what happens to its wavelength? This basically means that when the wavelength is increased, the frequency decreases and vice versa. The energy associated with a wave is directly proportional to its frequency. A high energy light will have a shorter wavelength than a low energy light. Similarly, as the frequency of a wave decreases, its wavelength increases. Because of this, as the wavelength increases (the waves get longer), the frequency decreases (fewer waves pass). The period of a wave is defined as the time taken by a wave to complete one full cycle or to complete an oscillation. As the frequency increases, the wavelength decreases. 3890 kb/s.

More formally, the frequency is inversely proportional to the period. Adjustment Effect on wavelength Effect on wave speed Increase amplitude stays the same stays the same Increase frequency decreases stays the same Increase tension increases increases Increase density increases decreases. R = 1.097 x 107 m-1. We can also observe that the waves are produced with a shorter wavelength. Frequency is the wavelength which effects the speed of electrons while intensity is the brightness which effects the number of electrons. So the longer the wavelengths and lower the frequency results in lower energy. 1. An increase in frequency produces a proportional decrease in the wavelength of light with a corresponding increase in the energy of the photons that make up the light. Consider the transverse wave on a slinky. Now, the new frequency of the wave = (2/3)f. Hence, the new wavelength of the wave is three and a half times its old wavelength.
