What is the wavelength of an x-ray photon with energy 8.0 kev (8000 ev)? (1 ev = 1.60 × 10−19 joule.)

what is its frequency?

Wavelength = 0.15 nm

Frequency =

Explanation:

We have given photon energy E = 8 KeV = 8000 eV

In question it is given that

So

Plank's constant

We know that photon energy is given by

So

Now wavelength

c

explanation:

i believe the answer is c and this is only worth 10 points you might wanna change it

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
