### Einstein's Equation: E=hv

What does the h in E=hv represent again??

### Re: Einstein's Equation: E=hv

The h is Planck's constant, which is equal to 6.63 x 10^-34

Planck's constant, defined as 6.63*10^-34 Joule*seconds

Also, it is important and useful to know that 'E' will be in joules since that is the standard measurement of energy and is taken from Planck's constant.

the equation shows that the energy per photon is proportional to frequency. As frequency increases, so does the energy per photon. Planck's constant, h, is the proportionality constant that equates v to E.

h is Planck's constant, which is 6.63*10^-34 J*seconds and I believe it will be given on the formula sheet for tests.

H is a constant and it is given to us.

The variable h in this equation, as my classmates have said, is Planck's constant and it's equal to 6.626*10^(-34). It has units of [J*s] which can also be converted to [kg*m^(2)*s^(-1)]. It will be given to us on exams.

Lavelle posted the formula sheet he will be giving us on tests on his website so if you ever want to check which numbers/equations he will give to us, it will be there for your reference

In chemistry, h is typically used to denote Planck's constant. It is a very small value equivalent to 6.626 times 10 to the -34 th power m^2 kg/s.

H is planks constant - 6.63 x 10^-34 J.s
But this is given to us in the formula sheet, so no worries!
