We know that E =m c2=(h c/λ) ∴ λ =(h/m c) or m =(h/λ c) Where, λ= wavelength of photon h = planck's constant m = mass of photon c = velocity of light Given, λ =3.6 mathringA=3.6 × 10-10 m ∴ m =(6.62 × 10-34/3.6 × 10-10 × 3 × 108) =6.135 × 10-33 kg

Q. The mass of a photon with wavelength $3.6 \overset{˚}{A}$ is:

$6.135 \times 10^{- 29} k g$

$3.60 \times 10^{- 29} k g$

$6.135 \times 10^{- 33} k g$

$3.60 \times 10^{- 27} k g$

Q. The mass of a photon with wavelength 3.6A˚ is:

6.135×10−29kg

3.60×10−29kg

6.135×10−33kg

3.60×10−27kg

We know that E=mc2=λhc​ ∴λ=mch​ or m=λch​ Where, λ= wavelength of photon h= planck's constant m= mass of photon c= velocity of light Given, λ=3.6A˚=3.6×10−10m ∴m=3.6×10−10×3×1086.62×10−34​ =6.135×10−33kg

Q. The mass of a photon with wavelength $3.6 \overset{˚}{A}$ is:

$6.135 \times 10^{- 29} k g$

$3.60 \times 10^{- 29} k g$

$6.135 \times 10^{- 33} k g$

$3.60 \times 10^{- 27} k g$
