Title: Karnataka Board 2nd PUC Physics Model Paper- Set 1 Author: BYJU'S Subject: Physics The second term, due to Spin-Orbit interactions, is harder to derive correctly. Q10. Two thin convex lenses of focal length f₁ and f₂ are placed in contact: a. The atomic weight of natural boron is 10.81. Great inventions don’t happen overnight. Question 14 (a) Half life of a certain radioactive material is 8 hours. Also find the wavelength of the first member of Lyman series in the same spectrum. Calculate the frequency associated with a photon of energy 3.3 × 10–20 J. Q11. Explain the hydrogen spectrum on the basis of Bohr's theory. Give principle used in the distillation technique. Symbol of a diode is given below: a. Frequency of any line in the series on the spectrum of hydrogen is expressed as the difference between the two atoms fcm = cRZ2[1/(n+p)2 – 1/n2] where m = n + p Substituting for p we get, fcm = (2cRZ2/n3)p 12.23. From IIT to Harvard and now BYJU’S, Tannishtha Sanyal is charting her own course. Q5. Mention its nuclear reaction which takes place in a nuclear reactor? ... two electrons from the electron transport chain combine with a hydrogen ion and NADP+ to form NADPH. Chapter–13: Nuclei Composition and size of nucleus, Radioactivity, alpha, beta and gamma particles/rays and their properties; radioactive decay law, half life and mean life. Hydrogen Fine Structure When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. (b) State the effect of the following changes on the X-rays emitted by Coolidge X-ray tube: (2) (i) High voltage between cathode and anode is increased. Byjus Asked on June 8, 2016 in ... Other pigments, called accessory pigments, enhance the light-absorption capacity of the leaf by capturing a broader spectrum of blue and red wavelengths, along with yellow and orange wavelengths. energy levels, hydrogen spectrum. 6. This splitting is called fine structure and was one of the first experimental evidences for electron spin. We understand the basis for this term. The Figure below shows the atomic emission spectrum of hydrogen. Like all the fine structure corrections, this is down by a factor of order from the Hydrogen binding energy.
