WebThe light visible to the human eye lies between 790 to 400 terahertz, and we are most sensitive to the greenish light at 540 terahertz. It must be noted that visible light is only a small portion of the entire electromagnetic spectrum. There are UV rays, Infrared rays, microwaves, radio waves, gamma rays, and X rays. WebScience Physics Assume the following waves are propagating in air. Part A Calculate the wavelength ₁ for gamma rays of frequency f₁ = 6.50×1021 Hz. Express your answer in meters. View Available Hint (s) X₁ ΑΣΦ Submit Part B Complete previous part (s) Part C Calculate the wavelength X₂ for visible light of frequency f2 = 6.35×10¹4 Hz.

WebThe speed is easy. It turns out that all electromagnetic waves have the same speed, which scientists represent with the letter c. This speed, the speed of light, is equal to 670 million miles per hour. The frequency can be any number. It is measured in Hertz, which means "One ripple per second." WebGamma rays, being the highest in frequency and energy, are the most damaging. Luckily though, our atmosphere absorbs gamma rays from outer space, thereby protecting us … The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, a… good methods for memorization
