The energy difference between adjacent orbit radii in a hydrogen atom remains co

Question

The energy difference between adjacent orbit radii in a hydrogen atom remains constant for all values of n. varies randomly with increasing values of n. decreases with increasing values of n. increases with increasing values of n. When an electron jumps from an orbit where n = 4 to one where n = 3 two photons are emitted. a photon is absorbed. a photon is emitted. two photons are absorbed. The distance between adjacent orbit radii in a hydrogen atom remains constant for all values of n. decreases with increasing values of n. varies randomly with increasing values of n. increases with increasing values of n. In the Bohr theory the orbital radius depends upon the principal quantum number in what way? N^3 1/^n^2 1/n n n^2 In a He-Ne laser, the actual emission line at 632.8 nm comes from a jump down in what atom(s)? helium and neon hydrogen helium neon oxygen If a star has a peak intensity at 580 nm, what is its temperature? 5000 K 5000 degree F 5000 degree C 2000 degree C 2000 K What is the surface temperature of a star, given that its radiation peak occurs at a frequency of 1.86 times 10^15 Hz? 20, 400 K 19,000 K 17,000 K 18,000 K 14, 500 K The surface temperature of the star is 6000 K. What is the wavelength associated with the light emitted by this star? 311 nm 907 nm 502 nm 483 nm 492 nm If sunlight peaks at 0.55 mu m wavelength, this infers a surface temperature of the sun of how many thousand degrees Kelvin? 5.3 25. 15. 9.5 2.5
