A wave with a low frequency has a long wavelength and low energy. Energy also travels along the slinky. 30 seconds. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. Since they are small enough to be considered quantum particles, photons can exist as waves, with a wavelength () corresponding to the distance between each repeating point in the wave. Throughout his life as a carpenter, Jeff Wilson has been making plans What Is The Difference Between Wavelength And Frequency?

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. The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases. To summarise, waves carry energy. b. The relationship between frequency and wavelength can be described.. answer choices. As explained in the other answers, decreased wavelength (at constant intensity) will actually decrease the current. On the electromagnetic spectrum, this corresponds to the range of visible light, along with some overlap with the infrared and ultraviolet regions. The above graph clearly indicated that, as the wavelength increases, the energy associated with the particle decreases exponentially. if E increase f has to increase. Question 7.
