(a) The wavelength of a Balmer series line (from n 1) or by found to be 656.5 nm. What percentage difference is found between this
and the wavelength predicted byž = R ()
[R = 1.097 x 107m]

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
