What is the photon energy (eV) of indigo light

1 answer:

7 0

Answer:

When dealing with "particles" such as photons or electrons, a commonly used unit of energy is the electron-volt (eV) rather than the joule (J). An electron volt is the energy required to raise an electron through 1 volt, thus a photon with an energy of 1 eV = 1.602 × 10-19 J.

Answer:

$\sqrt{\dfrac{2g\lambda^3}{m}}$

Explanation:

We can write the expression here, but the point of the problem seems to be to see if you can manipulate the controls on the answer box to reproduce that expression.

$\boxed{\sqrt{\dfrac{2g\lambda^3}{m}}}$

How is frequency related to the sound we hear?

Leviafan [203]

Frequency is the vibration of noise and the vibration determines the pitch, which we depend on to be a pitch or frequency we can hear. If it's too high or too low our ears can't hear it
