Question

X rays are used in hospital to locate in the patients bones.If the x rays of wavelength of 2×10 to the power negative nine m travel at a speed of 3×10 to the power eight m/s in air, what will be it's frequency?​

Answer 1

Answer:1.5×10 to the power of 17(unit-Hertz/H)

Explanation:V=F×Wavelength

F=V/Wavelength=3×10 to power/2×10 to power of -9=1.5×10 to power of 17
