Answer:
Explanation:
relation between energy wavelength and frequency.....
we know that energy of photon is
E=hf but
v=fλ
f=v/λ when v=c(speed of light) then f=c/λ
putting the value of f in the equation of photon
E=hc/λ this equation gave a relation between wavelength frequency and energy in electromagnetic waves
among electromagnetic waves UV rays are most dangerous because exposure to these radiation cause serious problems in living organism
