The brightest light deteected from the star Antares has a frequency of about 3.2X10^14 HZ. The speed of light is 3X10^8 m/s. What is the wavelegnth of this light?
It is approx 93.7 GHz.
9.4 x 10 ^9
Velocity equals frequency times wavelength
For electromagnetic radiation,c = speed of light = 3.0 x 108 m/s = frequency x wavelengthAs the frequency of light waves increase, the wavelength decreases. For electromagnetic radiation, the wavelength times the frequency equals the speed of light, c, which is 3.0 x 108 m/s. So, if the frequency increases, the wavelength will decrease, and if the wavelength increases, the frequency decreases.
Energy = Plank's constant times the speed of light divided by the wavelength of the electromagnetic radiation in question. as a formula: E = h * c / lambda E - energy h - Plank's constant c - speed of light lambda - wavelength
f=c/lambda frequency = 299792458 divided by wavelength The freq is in Kilohertz, and the wavelength is in meters. A nanometer is one billionth of a meter. I'll let you figure out how to move the decimals points.
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
For any wave, (wavelength) times (frequency) = (speed of propagation).For electromagnetic waves, (wavelength) times (frequency) = (speed of 'light')
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
The product of (wavelength) times (frequency) is equal to the speed of the wave.
Velocity equals frequency times wavelength
Electromagnetic radiation can travel through "empty" space. Depending on the wavelength of the electromagnetic radiation, we call it "radio" or "microwaves" or "heat" or "light" or "UV" or "X-rays" or even "cosmic rays" - it's all different frequencies of EM radiation. The shorter the wavelength, the higher the frequency; in fact, the frequency times the wavelength is the constant "c", the speed of light.
Electromagnetic radiation, which includes light and x-rays, travels at 299,792,458 metres per second (c - a universal constant). Speed, frequency and wavelength are related by the equation speed = frequency times wavelength. The only problem with this question is that a frequency of 2.01018 Hz is not in the x-ray range of frequencies. X-rays are found in the frequency range of 30 petaHertz to 30 exaHertz. To put it another way, electromagnetic radiation with a frequency of 2.01018 Hz has a wavelength of 149,137 kilometers (92,669 miles), and that's no X-ray.
For electromagnetic radiation,c = speed of light = 3.0 x 108 m/s = frequency x wavelengthAs the frequency of light waves increase, the wavelength decreases. For electromagnetic radiation, the wavelength times the frequency equals the speed of light, c, which is 3.0 x 108 m/s. So, if the frequency increases, the wavelength will decrease, and if the wavelength increases, the frequency decreases.
Energy = Plank's constant times the speed of light divided by the wavelength of the electromagnetic radiation in question. as a formula: E = h * c / lambda E - energy h - Plank's constant c - speed of light lambda - wavelength

The energy of a photon of electromagnetic radiation is(Photon's frequency) times (Planck's Konstant) .
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
Light is electromagnetic radiation. The speed of light in a vacuum is the speed for all electromagnetic radiation, as long as it is measured in vacuo.When e-m radiation travels through something other than a vacuum, it travels more slowly. How much slower sometimes varies according to the wavelength of the radiation.
