Question #e63cd

1 Answer

Jun 8, 2017

$3.02 \cdot 10^{- 28}$ $3.02 * 10^-28$

Explanation:

$E = h \frac{c}{λ}$ $E = hc/lambda$

$h$ $h$ - Plank's constant = $6.625 \cdot 10^{- 34}$ $6.625 * 10^-34$

$c$ $c$ - Speed of light = $3 \cdot 10^{- 8} m s^{- 1}$ $3 * 10^-8 ms^-1$

$λ$ $lambda$ - Wavelength

E = $\frac{6.625 \cdot 10^{- 34} \cdot 3 \cdot 10^{8}}{656.3}$ $(6.625 * 10^-34 * 3 * 10^8 )/656.3$

E = $3.02 \cdot 10 - 28 J$ $3.02 * 10-28 J$
