620 nm 1 m 109 nm 620107 m 620 nm 1 m 10 9 nm 620 10 7 m. As usual heres a calculator to make the work a little easier for you. If its wavelength is 24cm determine how fast it is moving.
L 300 x 108 ms 509x1014s 589 x 10-7 m or 589 nm.
Use the correct units. Given the wavelength of the photon particle 500 nm. Calculate wavelength with the wavelength equation. R E -2178 x 10-18 J it is negative because energy is being emitted l.
