WebWhen a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. Rarely however does just a single frequency of light ... WebFor an electromagnetic wave to travel the distance of one of its wavelengths, λ, at the speed of light, c, we have c = λ/ t. The frequency of a wave is the number of cycles per second. If a wave has a frequency of a million cycles per second, then the time for each cycle to go by is a millionth of a second. So, in general, t = 1/ f. sonic hungryWebwaves. In empty space, light has a fixed speed and the wavelength can be measured. In the past 300 years, scientists have improved the way they measure the speed of light, and they have determined that it travels at nearly 299,792 kilometers, or 186,281 miles, per second. When we talk about light, we usually mean any radiation that we can see. sonic hunger games simulator
