Mosley studied the characteristic X-ray spectrum of a number of a heavy elements and concluded that the spectra of dissimilar elements are very same and with enhancing atomic value, the spectral lines merely goes towards higher frequencies.
He also gave the following relation
where v = Frequency of emitted line, Z = Atomic number of target, a = Proportionality constant, b = Screening constant.
A hiker tosses a rock into a canyon. He hears it strike water 4.78 s later. How far down is the surface of the water?
is it possible for an element to have different types of atoms/Explain/
The measurements taken in Ramdesns eyepiece more worthy (reliable) than Huygens eyepiece. Why? Describe critical angle. show its relationship with refractive index.
A helium atom is in a galaxy travelling at a speed of 4.89 x 10 6 m/s away from the Earth. An astronomer on Earth observes a frequency from the helium atom of 6.52 x 10 14 H
