Aphoton has a wavelength of 3.8 x 10^-7 meters, what is the energy of this photon?

Wavelength of photon, λ = 3.8 × 10-7 meters

Frequency of photon,  

Thus, energy of photon,  

= 5.2276 × 10-19 joules

The energy of a photon having a wavelength of 3.8 × 10-7 meters is 5.2275 × 10-19 joules.

i can ! i just need to know what the paragraph is! : p

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
