Question
A particle has a velocity that is $90 . \%$ of the speed of light. If the wavelength of the particle is $1.5 \times 10^{-15} \mathrm{~m}$, calculate the mass of the particle.
Step 1
First, we need to find the velocity of the particle. We know that it is 90% of the speed of light, so we can calculate it as follows: v = 0.9 * c v = 0.9 * (3 * 10^8 m/s) v = 2.7 * 10^8 m/s Show more…
