Explanation:

energy of 1 photon =hc/wavelength(#)

1J=n 6.6*10^-34 X 3*10^8/(7000*10^-10)

n=3.53*10^18( by calculator)

Answer:

Energy = n × hc/λ

n = Energy × λ / (hc)

= 1 J × 7000 × 10^-10 m / (6.626 × 10^-34 J s × 3 × 10^8 m/s)

= 3.5 × 10^18 photons

= 3.5 Quintillion photons

Number of photons = 3.5 Quintillion

plz mark as brainliest!!!

plz plz plz plz plz plz plz plz plz
