The wavelength of the light determines its characteristics. It does not store any personal data. What are 6 of Charles Dickens classic novels? What experience do you need to become a teacher? (increase or decrease) 4. 2. The order from the weakest to the strongest to weakest. So if you wavelength gets shorter (i.e., energy for each photon increases), then given constant intensity you will have fewer photons, i.e., fewer electrons are removed from the material, i.e., smaller current (but those electrons will have higher energy). Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. This cookie is set by GDPR Cookie Consent plugin. What type of electrical charge does a proton have? So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. How does the wavelength change when you increase or decrease the frequency does it vary as expected explain? What happens to the wavelength of a photon after it collides it collides with an electron? They'd both meet the requirement. Putting a lot of energy into a transverse pulse will not effect the wavelength, the frequency or the speed of the pulse. Since the dispersion relation of water waves is such that longer wavelength waves propagate faster, you have your answer. It does not store any personal data. Address It also does not affect wave speed. When this happens, the light is reflected in all directions due to the variations in the characteristics of the surface or particle. From these equations you may realize that as the frequency increases, the wavelength gets shorter. (i) 2V . Equivalently, the longer the photons wavelength, the lower its energy.
