Answer: 1.1·10^5 m/s Explanation: speed = wavelength · frequency v = λf and frequency f = 1/T , in which T = period Speed v= λ/T = 3.2·10^-7 m /2.8·10^-12 s = 114285,7 m/s Reply
Answer: 1.1·10^5 m/s
Explanation: speed = wavelength · frequency v = λf and
frequency f = 1/T , in which T = period
Speed v= λ/T = 3.2·10^-7 m /2.8·10^-12 s = 114285,7 m/s
