Question

The wave length of tge first line of the Balmer series in hydrogen spectrum is 'x! A ^ 0 . Then the wave length (in * A ^ 0) of the first line of Lyman series in the same spectrum is 1) 5/27 * x 3) 27/5 * x 2) 4/3 * x 4) 5/36 * x​

Answer 1

Answer:

Calculate the angle at which the first dark band and the next bright band

formed in the single slit diffraction pattern of slit width 0.3 mm. Given λ=

5890Å338 m/s) Blue light of wavelength 480rom illuinates diffraction grating. The second order image is formed at an angle of 30° from the central a centimeter are there on the grating? image. How many lines inthe figures have same shape and size are called congruent
