Compose the expression for a quantity whose dimension is length, using velocity of light c, mass of a particle m, and Planck's constant h. What is that quantity?

Answer»

Solution :The unit of `cancelh` is Jpule.sec. Since `mc^(2)` is the rest mass enegry, `(cancelh)/(mc^(2))` has the dimension of TIME and multiplying by `c` we get a QUANTITY
`cancellambda_(c) =(cancelh)/(mc)`.
whose dimension is lingth. This quantity is called reduced compton wavelength.
(The NAME compton wavelengths is traditionally reserved for `(2PI cancelh)/(mc))`.
