and this problem. We're asked to calculate the wavelength of a proton moving at 1% of the speed of light. So our wavelength is going to be equal to our planks. Constant, divided by linear momentum and linear momentum is mass times velocity. So our wavelength is plants constant, divided by mass times velocity know our velocity here is going to be 1% of the speed of light, so 0.1 time seat. So for plants constant, we can use the 6.63 times tension in negative 34 jewels per second value. And our mass of our proton is 1.67 times 10 to the negative 27. And our speed of lights is three times tend to the eighth meters per second gives us a wavelength of 1.3 times 10 to the negative 13 meters.
