- The characteristic K, and K, lines for titanium have wavelengths of 0.275 nm and 0.251 nm, respectively. What is the ratio of the energy difference between the levels in titanium involved in the production of these two lines? AEIf the tunneling current is 8.7 pA when an STM probe is 0.40 nm from a surface and 17 pA when the probe is 0.5 nm from the surface, calculate the current on moving the tip in 0.10-nm steps from 0.40 nm to 1.50 nm.The main equation we are using to measure the e/m ratio is: (e/m)=((2v)/(r2B2)) If the anode voltage V is increased by 4 times and the magnetic field was kept constant, the electron beam's deflection radius will be doubled. If we plot V as the y-axis and r2 as the x-axis the slope is equal to: A) (e/m)B2=slope B)(e/m)=slope C)(e/m) (B2/2)=slope
