E=1.32E-17 J

Explanation:

First compute frequency $v = \frac{c}{λ}$ $v=c/lambda$
Then $v = \frac{300000000}{0.000000015}$ $v=300000000/0.000000015$ You wil get frequency as $v = 2 E 16 h e r t z$ $v=2E16 hertz$
Now you can compute the radiant energy by $E = h \cdot v$ $E=h*v$ where h is Planck's constant (6.6E-34 J*s)

$E = 2 E 16 \cdot 6.6 \cdot E - 34$ $E=2E16*6.6*E-34$
$E = 1.32 E - 17 J$ $E=1.32E-17 J$
