Could you guys verify if the correct answer is B because of the v^2? d. As the wavelength of a photon increases, its frequency decreases. < > As wavelength decreases, frequency 0 O 3.) So the longer the wavelengths and lower the frequency results in lower energy. The speed of light, c is a constant, so when wavelength decreases, frequency increases and vice versa. The number of complete wavelengths in a given unit of time is called frequency (f). Energy is directly proportional to frequency and frequency is inversely proportional to the wavelength of the radiation. Gamma rays Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

To make pattern 1, people have to shake the slinky back and forth at a certain speed. 7. b. The relationship between energy (E), frequency and wavelength can be described with this equation: Since all that waves really are is traveling energy, the more energy in a wave, the higher its frequency. Students might also compare the size of the wavelength of various waves to the sizes of common objects, as illustrated in the above figure. Let f and F be the old and new frequencies of the light wave. I am currently continuing at SunAgri as an R&D engineer. The velocity, frequency, and wavelength of a wave are related by the equation: velocity = frequency x wavelength; Therefore, if the velocity of the wave is 120 m/s and the frequency is 5 Hz, the wavelength can be determined as follows: wavelength = velocity / frequency wavelength = 120 m/s / 5 Hz wavelength = 24 m Consider the transverse wave on a slinky. southwest (that is, at 45 degree from directly south and from directly west), vector d2 for 0.50 m due east, vector d3 for 0.60 m at 60 degree north of east. They are related by = hc/ E photon where h is Plank's constant, c is the velocity of light and is the wavelength of the photon. What is the highest frequency ever recorded?
