By the energy-momentum relation, photons are relativistic particles since they travel at the speed of light. In this short text, we will introduce you to the photon energy equation and its relation with its wavelength. The best wavelengths of light for photosynthesis are those that are blue (375-460 nm) and red (550-700 nm). Just remember that electron and positron will have the mass of 2me2\ m_{\rm e}2me in total. With a simple substitution, we find the formula to calculate the energy from the wavelength and vice versa: E = h\cdot \nu = \frac {h\cdot c} {\lambda} E = h = h c. In the following section, we will analyze the equation for energy and wavelength, how to calculate some of the results, deal with the measurement units, and more. As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa. The 1J\small 1\ \rm J1J of energy "weights": where c2.998108m/s\small c \approx 2.998 \times 10^8\ \rm m/sc2.998108m/s is the light speed. v = 3.0 x 10^8 m/s k = 2 Would it not make sense that in order to convert energy in joules to wavenumber we multiply E by 2 h c = 1 c. So my question is why in converting energy from the units of joules to the units of wavenumber do we divide E by h c rather than by c quantum-mechanics dimensional-analysis Share Cite Improve this question Follow For example: Find the frequency of a wave with wavelength 2.5 m and speed 50 m/s. How to convert between wavelength and energy of a photon. One calorie is the amount of thermal energy necessary to raise the water temperature by one degree (in the temperature of 14.5 degrees Celsius). Convert energy into joules (J).
