What is If an electromagnetic wave has a frequency of 7.57 times 10 to the power of 14 hertz What is its wacelength and to what part of the spectrum does this wave belong?

Frequency of an electromagnetic wave = c / lamba
c = the speed of light = 29979245800 cm/s
lamba (sorry, don't know how to write it on the computer) = wavelength in cm.
Therefore if we assume that your wavelength is 0.07 cm (next time, please remember your units), then your frequency = 29979245800/0.07 = 428274940000 cycles/second (which looks quite off, so I'm assuming that your 0.07 was in meters and not centimeters. In that case convert 0.07m to 7 cm and plug in the formula.)

∙ 9y agoSomething measured in meters is NOT a frequency. Frequency is measured in Hertz, equivalent to cycles per second. Once you have a valid frequency, you can divide the speed of light (3 times ten to the power 8 meters/second) by this frequency to get the wavelength. Similarly, if you meant that that is the wavelength and you want to find the frequency, you can divide the speed of light by the wavelength. With SI units, the speed of light should be expressed in meters/second (with the numbers I mentioned above), the frequency in hertz (= cycles/second), and the wavelength in meters.

∙ 9y ago4.6 x 10^(-7) m, or 460 nm, is not a frequency; it is a length. Electromagnetic radiation with a wavelength of 460 nm is blue light. The frequency of the light can be found by dividing the speed of light by the light's wavelength (f = c ÷ λ).f = (3 x 10^8 m/s) ÷ (4.6 x 10^-7 m)≈ 0.652 x 10^15 Hz = 6.52 x 10^14 Hz = 652 THz (652 terahertz)

Which part of the electromagnetic spectrum will a photon belong if its wavelength in a vacuum is 5.6 10 -7 meter?
X ray
What type of wave is infrared wave?
Infra red waves are light waves that are just below human perception at the red end of the spectrum.They belong to the electromagnetic wave spectrum.
Light waves belong to which category of waves?
Electromagnetic radiation.
What determines the color of an light?
Light is part of the electromagnetic radiation spectrum. It is the range of the spectrum that the human eye can see. It's wavelength goes from about 380 nm to about 740 nm. The different colors of light belong to different wavelengths. You'll find violet on the short wavelength side and red on the long wavelength side. Below the wavelength of 380 nm you find Ultra Violet light and above 740 nm you find the Infra red light, both not visible to the human eye.
Why in an absorption spectrum the back ground is bright and the lines are dark?
Because it is an absorption spectrum. An absorption spectrum begins with a source of pure white light. This hits a prism which spreads it out into a spectrum and the result shows on a screen as a bright band of colours. If you put this into a glass case and seal it to the outside world, nothing changes. Now if blow a gas into the tank, the atoms in the gas absorb different wavelengths (colours) of light. The result you see is a normal spectrum of colours, but with one or more dark lines across it. This is because the atoms in the gas through which the white light is shining are absorbing some or all of various colours in the spectrum. What those colours are is absolutely characteristic and definitive of that particular gas. This is a very powerful technique for identifying elements which are present only in trace amounts. An interesting light on this is that the element Helium was first discovered not on earth, but on the sun by some dark lines in the sun's spectrum which did not belong to any known element.
What does belong in the electromagnetic spectrum?
uhm I guess infrared rays
What does not belong in the electromagnetic spectrum x-ray or sound or infrared ray or radio wave?

Electromagnetic radiation.
Which element on the periodic table is used to kill cancer cells?
In terms of the Electromagnetic spectrum, Gamma radiation and X-rays are usually used to treat cancer patients in a process called Radiotherapy, as these are the highest energy forms of the EM spectrum. However, other forms of radiation such as high-energy neutrons are being used, which do not belong to the EM spectrum.

What is the mass number of a gamma particle?
Gamma rays belong to the electromagnetic spectrum. In frequency and consequent energy the spectrum runs from very very long low energy radio waves up to the highest energy and frequencies which include gamma rays. Somewhere between those very low energies and the highest energies lies the visible light frequencies and energies. You know them as ordinary light. And I suspect you've heard light consists of photons, which are massless. I mention the visible light to point out that gamma rays belong to the same EM spectrum so they too are made of the same stuff that visible light is made of...photons. And photons have no mass; they are massless bits of energy. In short, gamma particles, which are photons, have no mass. ANS.
What is a Doppler red shift and a Doppler blue shift?
A Doppler red-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward longer wavelengths. Such a shift can be caused by the star's moving away from us, and that's how it's interpreted when astronomers see it. A Doppler blue-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward shorter wavelengths. Such a shift can be caused by the star's moving toward us, and that's how it's interpreted when astronomers see it.
