An x ray tube has an applied voltage of 100 kv.

a. what is the most energetic x-ray photon it can produce? express your answer in electron volts and joules.
b. find the wavelength of such an x—ray.

To solve this problem we will apply the concepts related to Energy in a photon and the electric potential energy. With these two definitions we can solve the first two points. The energy in a photon is described under the mathematical relationship

Here,

E = Energy of photons

h = Planck's constant

c = Speed of light

Wavelength

At the same time the electric potential energy is defined as

E = qV

Where,

q = Charge of electron

V = Voltage

PART A ) The charge of the electron is a constant while the voltage was previously given, therefore

PART B) From the first definition, about energy in a photon, we can use it to find the wavelength. Energy is therefore conserved, the previously found value will serve us for that variable. The other two terms are constant, so replacing

Therefore the wavelength of the X-ray is

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
