Help and explain how to convert it pls

Answer : The correct answer is option (3)

Explanation: Given,

Wavelength =  350 nm =        

Now we have to determine the energy of photon.

Formula used:

where,

E = energy  of photon

h = Planck's constant =  

c = speed of light =  

= wavelength of photon

Now putting all the given values in this formula, we get:

Therefore, the energy of photon is,

air quality

poor drinking water

and heavy polution

can lead to poor health

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
