Answer:
Frequency,
Explanation:
Given that,
The wavelength of the x-rays,
We need to find the frequency of an x-ray. All electromagnetic wave travel with a speed of light. It is given by the formula as :
f is the frequency
So, the frequency of an x-ray is . Hence, this is the required solution.
Answer:
Explanation:
Let's use the equation that relate the temperatures and volumes of an adiabatic process in a ideal gas.
.
Now, let's use the ideal gas equation to the initial and the final state:
Let's recall that the term nR is a constant. That is why we can match these equations.
We can find a relation between the volumes of the initial and the final state.
Combining this equation with the first equation we have:
Now, we just need to solve this equation for T₂.
Let's assume the initial temperature and pressure as 25 °C = 298 K and 1 atm = 1.01 * 10⁵ Pa, in a normal conditions.
Here,
Finally, T2 will be:
