Question

which of the following corresponds to maximum frequency a) 3eV b) 3J c)3Kj d) 2Kj mol^-1​

Answer 1

Answer:

[E=h\nu$$

E is the energy of photon, h is the planck's constant, ν is the frequency of the light. Therefore,

ν=Eh=3.6x10−19J6.63x10−34m2kgs−1=5.4x1014s−1(1)

c=λν(2)

c is the speed of light, λ is wavelength.

λ=cν=3.0x108ms−15.4x1014s−1=5.6x10−7m=560nm(3)

thank you.
