According to the law of reflection,

when two waves meet, they reflect
when two waves meet, they interfere
when a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave
when a wave meets a boundary, the angle of the refracted wave will be equal to the angle of the incident wave

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
