Q: one of the electron transitions in a hydrogen atom produces infrared light with a wavelength of 7.464 × 10 -6 m. what amount of energy causes this transition? this is the answer i got. is that right?a: v=2.998 x 108 m m-1 / 7.464 x 10-6 m v=4.017 x 1013 e=6.626 x 10-34 x 4.017 x 1013 26.616642 x 10-21 e=2.662 x 10-20

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
