Find the wavelength (in nm) of a photon whose energy is 5.90 x 10-19 J. I understand that I have to use this equation to figure out the problem E=nhf, I just keep getting the wrong answer. Which is 33.68 nm

As Section 27.5 discusses, sound waves diffract or bend around the edges of a doorway. Larger wavelengths diffract more than smaller wavelengths. (a) The speed of sound is 343 m/s. With what speed would a 57.0 kg person have to move through a doorway to diffract to the same ex...

Interesting. Im glad I wasn't to far off on the answer. Makes me feel a little better about everything. Thank you so much!!!

A woman is 1.6 m tall and has a mass of 53 kg. She moves past an observer with the direction of the motion parallel to her height. The observer measures her relativistic momentum to have a magnitude of 2.6 x 1011 kg·m/s. What does the observer measure for her height?

Thank you. i sort of had to back track to get the answer you got but eventually got it. Thank you!!
