As the wavelength of a photon increases, its frequency decreases. Frequency is inversely proportional to amplitude. X-rays or gamma-rays are examples of this. A higher amplitude sound wave is a louder sound. Difference between Center of Mass and Center of Gravity, Differences between heat capacity and specific heat capacity'. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. 14. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. Energy and amplitude. If a wave whose frequency is 6 kHz has a wavelength of 100 mm, then find the wavelength of the wave whose frequency is 5.4 kHz. 1, the wavelength of ice-covered sea (the distance between two consecutive wave crests) can be different from that of open-water condition (see Fig. Wavelength is the distance between two crests or two troughs as shown in Fig. If the reck has a mass of $50 \mathrm{~g}(0.05 \mathrm{~kg})$; what is its maximum possihle velocity after relesse? In this concise guide, well cover all you need to know about the relationship between wavelength, frequency and energy in the context of photons and the electromagnetic spectrum.
