Answer:
m=-25
Step-by-step explanation:
m=Δh/Δt
(Im choosing for the difference in height and time (Δh and Δt) to be the difference between the data in the first two rows)
m=(4500-5000)/(20-0)
m=-500/20
m=-25
Answer:
![\lambda=10^{-10}\ m](https://tex.z-dn.net/?f=%5Clambda%3D10%5E%7B-10%7D%5C%20m)
Step-by-step explanation:
Given that,
The frequency of x-rays, ![f=3\times 10^{18}\ Hz](https://tex.z-dn.net/?f=f%3D3%5Ctimes%2010%5E%7B18%7D%5C%20Hz)
We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :
![v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m](https://tex.z-dn.net/?f=v%3Df%5Clambda%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7Bc%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B3%5Ctimes%2010%5E%7B8%7D%7D%7B3%5Ctimes%2010%5E%7B18%7D%7D%5C%5C%5C%5C%3D10%5E%7B-10%7D%5C%20m)
So, the wavelength for x-rays is
