Answer:
The energy of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, there is an inverse relation between the frequency and the wavelength :
(2)
Where is the speed of light, which is also a constant.
If we substitute (2) in (1) we will have the following:
(3)
This means, there is direct relation between the energy and the frequency and there is an inverse relation between the energy and the wavelength.
Since the product of P·Vis constant along an isotherm, an expansion to twice the volume implies a pressure reduction to half the original pressure. I hope my answer has come to your help. God bless and have a nice day ahead!<span>

Given a model that looks like that, I do experience severe upset. I'm not throwing up yet, but it's only a matter of time.
Answer:
486nm
Explanation:
in order for an electron to transit from one level to another, the wavelength emitted is given by Rydberg Equation which states that
Hence the photon must possess a wavelength of 486nm in order to send the electron to the n=4 state
Answer: Power of a lens is -2D, negative sign indicates it is a Concave lens. Focal length (in meters)=1/power of the lens, thus focal length=1/2=0.5m=50cm.Jul 6, 2019
