3 kHz= 3000 Hz C=?v 3.00 x 108 m/s= 3,000 1/sec (?) ?= 100,000 m= 100 km c: more than 1 km

(AM broadcast starts at 550 KHz and goes up from there.)

What happens to an electromagnetic wave's frequency as it's wavelength decreases?
The product of (wavelength) x (frequency) of any wave phenomenon is alwaysthe same number ... the speed of the wave. So if wavelength changes, thenfrequency must change by exactly the same factor in the opposite direction,in order for their product to remain constant.
The various types of electromagnetic radiation are distinguished from each other by their?
Electromagnetic waves are classified according to their wavelength and frequency and this classification is called electromagnetic spectrum.
What happens to the wavelength of a wave if the frequency is decreased?
In this case, the wavelength increases. The wavelength, multiplied by the frequency, is equal to the speed of the wave - and in most types of waves, the speed is more or less independent of the frequency.
How does the frequency of a gamma ray change as tis wavelength decreases?
Less wavelength implies more frequency. The product of wavelength x frequency is always the speed of the wave - in this case, the speed of light.
How does wavelength affect a wave's energy?
It really depends on the type of wave. In the case of electromagnetic waves, a higher frequency results in more energy per photon. Therefore, a longer wavelength results in less energy per photon.
How are the energy and the frequency of an electromagnetic wave related?
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.

What less energy a wave has the smaller its?
If it is a mechanical wave, then the lower amplitude waves would have less energy. If you are talking about electromagnetic waves, then higher frequency waves (shorter wavelength) have more energy, and lower frequency waves have less energy.
What happens to the you increase the wavelength?
Remember that wavelength x frequency = speed of the wave.If you increase the wavelength, the frequency will decrease - since the speed of most waves is more or less independent of the frequency or wavelength.

Electromagnetic waves with a longer wavelength has?
An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.An electromagnetic wave with a longer wavelength will have a smaller frequency, and less energy per photon.
What is the relationship between the energy and wavelength of electromagnetic radiation?
Wavelength and frequency are inversely proportional. The higher the frequency, the shorter (lower) the wavelength. Energy is proportional to frequency, and higher frequency waves will have a higher energy. Mathematically, frequency = 1 divided by wavelength, or f = 1/λ Use the link below for more information, including a diagram or two to make things clearer.

Is this true or false the shorter the wavelength of electromagnetic radiation the more energy carried by the wave?
This is true. Each photon carries more energy when it has shorter wavelength / higher frequency.
is light the only electromagnetic wave?
No. Visible light is actually a very small part of the electromagnetic spectrum which ranges from very short wavelength high frequency electromagnetic waves such as gamma radiation up to very long wavelength, low frequency electromagnetic waves such as radio waves. For more information on the electromagnetic spectrum and the small part of it made up of visible light, see the related link.
