Radio waves Radio waves have the longest wavelength, and gamma rays have the shortest wavelength. Because they have opposite electrical charges, electrons are attracted to the nucleus of the atom. What was the BONUS ROUND answer last night? Equivalently, the longer the photons wavelength, the lower its energy. What is are the functions of diverse organisms? Consider the reaction O3 + UV O2 + O*. How can global warming lead to an ice age. Using those symbols, the relationships between energy, wavelength and frequency can be written as wavelength equals the speed of light divided by the frequency, or = c / and energy equals Planck's constant times the frequency, or E = h Where: is the wavelength is the frequency E is the energy Gamma rays Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

The above expression suggests that when the temperature increases, then the length increases and then the frequency decreases. 6.11 What happens when we have both absorption and emission in the infrared? d. What happens to that energy? The different wavelengths and frequencies of various forms of electromagnetic radiation are fundamentally similar in that they all travel at the same speed--about 186,000 miles per second (approximately 300,000 kilometers per second), commonly known as the speed of light (and identified with the variable c ). A higher temperature will cause the wavelength of peak emission to be at a shorter wavelength. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.
