Best Answer

Use the fact that for any wave:frequency x wavelength = speed

In the case of light, the speed (in a vacuum) is about 300,000 km/second, so you simply need to divide that by the wavelength (also in km). The answer will be in 1/seconds, in other word, hertz.

What is the wavelength of an electromagnetic wave that has a frequency of 3 kilohertz?

Wavelength = (speed)/(frequency) = 300,000,000m/s/3,000(1/s) = 100,000 meters or 100 km


What type of relationship exists between wavelength and frequency?

the product of wavelength and frequency is speed of propagation for a vacuum about 300,000 km/s, about the same in air, less for glass or water


What is the equation for the relationship between frequency and wavelength?

Depends on the medium in which the wave is travelling. For radio frequency, the connection is the speed of light at 300,000,000 Km/sec Divide the speed of light by frequency in hertz (c/s) and it will give wavelength in metres.


Is there a wavelength for electricity?

Sure, if it is AC (alternating current), you can calculate a wavelength. For example, in copper the speed is roughly 2/3 the speed of light in a vacuum, that is, 200,000 km/sec.; electricity in our homes comes at a frequency of 50 or 60 cycles per second; so (assuming the frequency of 50 cycles), that would give you a wavelength of 200,000 km/sec / 50 Hertz = 4000 km.Sure, if it is AC (alternating current), you can calculate a wavelength.

What is the wavelength of a wave with frequency of 6.0 x 10 18?

speed = wavelength x frequency, so it can't be done unless you know the speed. However if it's an electromagnetic wave the speed is about 3 x 108 km/s so the wavelength is 3 x 108/6 x 1018 km = 5 x 10-11 km

What is the principle difference between radio waves and visible light?

Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )

No.


A sound wave has a frequency of 3 khz and wavelength 30 cm. how long will it take to travel 1.2 km?

Speed of sound in air isn't affected by frequency and wavelength, but it is of temperature, air pressure and humidity. Generally speaking speed of sound in air is about 340 meters/second.
