What is the frequency of light having a wavelength of 447 nm

What is the frequency of light having a wavelength of 447 nm?

What is the relationship between energy and the speed of light

There isn't any. The skinniest trace of light, so weak that the human eye can't

detect it, and the mightiest torrent of light from an exploding star, all travel at

the same speed, as long as the comparison is made in the same material.

Likewise, light with the lowest frequency/longest wavelength and light with the

highest frequency/shortest wavelength ... the properties that really determine the

energy carried by the light ... all have the same speed, as long as the comparison

is made in the same material.

Molybdenum-99 has half a half-life of 66 hours. after 132 hours how much of an initial sample of 10 ci of mo-99 would remain

What is the binding energy of a mole nuclei with a mass defect of 0.00084

7.56 x 10^13J / Mole

What is the first quantum number of a 1s2 electron in phosphorus

The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.
