If a wave has a wavelength of 10 mm and a frequency of 5.0 hertz what is the speed?

Wavelength= 10 mm. Frequency= 5.0 hertz. Speed= 50 mm/second (wavelength x frequency)

If an X-ray has a wavelength of 5 nm what is its frequency?

The formula is speed of light (3x108)=Wavelength in meters times frequency in hertz wavelength really=5x10-9 so frequency=6x1016 Hertz or cycles per second

What is the speed of a wave that has a frequency of 250 hertz and a length of 1.3 meters?

The equation to use in this case is:speed (of the wave) = wavelength x frequency If the frequency is in hertz, and the wavelength is in meters, the speed will be in meters/second.

What is the wavelength of a wave with a speed of 30 meters per second and a frequency of 10 hertz?

Wavelength = speed/frequency = 30/10 = 3 meters

If blue light has a frequency of 6.98 10 14 hertz what is the wavelength in nanometers?

Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.

What are the units of wavelenght?

there are no units for wavelength but wavelength frequency is in hertz

What do you mean by using the word wavelength?

The word "wavelength" refers to the frequency of a wave. Wavelength is measured in hertz; the number of vibrations per second.

What is the wavelength if the speed 331 meters per second and the hertz is 20.0?

331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.

Describe the wavelength of a sound wave?

The speed of sound is approximately 343 meters per second and the wavelength is then related to the frequency of the sound by L=343/frequency Thus a 343 Hertz tone have a wavelength of 1 meter and a 686 hertz tone have a wavelength of 0.5 meter.

What is the frequency of visible light with a wavelength of 506 nanometers?

Convert that to meters. Then divide the speed of light (in meters/second) by the wavelength. The answer will be in hertz.

What is the wavelength of blue light with a frequency of 6.82x1014 Hertz?

Wavelength is speed, of light, in this case, divided by frequency. 3 x 108 meters per second divided by 6.82 x 1014 Hertz is 0.4 micrometers.

What are the metric units for wavelength frequency?

Wavelength is a length. Hence, the metric unit for it is "meter". Frequency is a reciprocal of time. Hence, the unit for it is "per second", named "Hertz".
