When light of frequency twice the threshold frequency is incident on the metal plate, the maximum velocity of emitted electrons is \( v_{1} \). When the frequency of incident radiation is increased to five times the threshold value, the maximum velocity of emitted electron becomes \( v_{2} \). If \( v_{2}=x v_{1} \), the value of \( x \) will behttps://bit.ly/YTAI_PWAP https://www.pw.live
