E(energy)= hc/wavelength. ;
where h= plank constant and c=velocity of photon ( sun light )
h=6.626 \times 10 {}^{ - 34}
c=3 \times 10 {}^{8} m/s
wavelength= 550 nm=550 \times 10 {}^{ - 9} meter

so..
e = \frac{6.626 \times 10 {}^{ - 34} \times 3 \times 10 {}^{ 8} }{550 \times 10 {}^{ - 9} } \\ \: \: \: = 0.03614 \times 10 {}^{ - 17} \\ \: \: \: = 3.614 \times 10 {}^{ - 15}
so.. energy= 3.614*10^-15 Joule
I think this is right....
if this right.....
hope this helps.....
please mark as brainlist......
if this correct..... please mark...
