Suppose in certine condition only those transition are allowed to hydrogen atoms in which the principal quantum number a changes by 2 (a) Find the smaller wavelength emitted by hydrogen (b) list the wavelength emitted by hydrogen in the visible range (380 nm to 780 nm)

Find the wavelength in a hydrogen spectirm between the range 500nm to 700nm

Assume that lasers are available whose wavelengths can be precisely ''tuned'' to anywhere in the visible range-that is, in the range 450nmltlambdalt650nm . If every television channel occupies a bandwidth of 10 MHz, how many channels can be accommodated within this wavelength range?

Find the wavelengths in a spectrum of hydrogen atom between 600 nm to 700 nm

How many centimeters make 1 nm?

What lines of atomic hydrogen absorption spectrum fall withinthe wavelength range from 94.5 to 130.9nm ?

Absorption spectrum is obtained for a sample of gas having atomic hydrogen in ground state. Which lines of the spectrum will be in the range 94 nm to 122 nm . Take Rydberg’s constant R = 1.1 × 107 m^(–1)

In a double-slit experiment, the fourth-order maximum for a wavelength of 450 nm occurs at an angle of theta= 90^(@) . (a) What range of wavelengths in the visiblc range (400 nm to 700 nm) are not present in the third-order maxima? To eliminate all visible light in the fourth-order maximum, (b) should the slit separation be increased or decreased and (c) what least change is needed?
