An x-ray has a wavelength of 879 nm. What is the speed of the x-ray??

Question

Help? I don't get how you get the answer, please explain i don't only want you to tell me but show me!

Answer 1

Speed of Magnetic waves is c, is 300,000,000 meters per second, or 186,000 miles per hour.
The speed of an electromagnetic wave is always constant, no matter the frequency or the medium. I am sure of this.
Only the period changes.

The above numbers are very, very close approximations.

Answer 2

The speed of x-rays is the same as the speed of light, because x-rays are the same thing as light, but at a much higher frequency. The speed in a vacuum does not depend on the wavelength. The speed in a refractive medium is different at different wavelengths, but you would need to know the index of refraction and dispersion factor (Abbe Number) to compute the speed at 879nm

Answer 3

X-rays are a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometres, corresponding to frequencies in the range 30 to 30 000 PHz (1015 hertz).
Electromagnetic Radiation
See Fig.7.1 and The basic properties of waves - applet.
Key formula: To convert between wavelength and frequency use:


l (m) . n (s-1 or herz - Hz) = c where c = 2.9979 x 108 m.s-1

In chemistry we often use wavelengths expressed in nanometers ((1 nm = 10-9 m). (Fig 7.2)
Classification of
Electromagnetic Radiation
Region Wavelength
Gamma rays ~10-12 m
X-rays ~10-10 m
Ultra-violet (UV) ~10-8 m
Visible 4 x 10-7 to 7 x 10-7 m
Infra-red (IR) ~10-4 m
Microwaves ~10-2 m
FM radio ~1 m
Short-wave radio ~100 m
AM radio ~1000 - 10000 m

Answer 4

The speed of light is a constant and doesn't depend on wavelength.

Answer 5

299,792,458 metres per second, x-rays all have a constant speed (the same as the speed of light).

Answer 6

c or 2.99e8 m/s
because the electromagnetic spectrum speed is constant.
c= wavelength*frequency
