The mass of photon having wavelength 0.1nm is

1.	The mass of photon having wavelength 0.1nm is
Answer» he wavelength of the photon particle = 0.1 nm To find,The mass of the GIVEN photon particle. Solution,We can EASILY solve this mathematical problem, by using the following mathematical FORMULA. hc/λ = mc² (Here, h = Planck Constant, C = speed of light , λ= wavelength , m = mass)The above mentioned equation is derived from the Planck Einstein relation.Now, h = 6.626×10-³⁴ JS c = 3×10⁸ ms-¹ λ = 0.1 nm = 1 × 10-¹⁰ m By putting the values, we GET the following mathematical equation,mc² = hc/λ m = hc/λc² m = h/λc m = (6.626×10-³⁴)/(1 × 10-¹⁰×3×10⁸)m = (6.626/3) × 10-³²m = 2.21 × 10-³² kg Hence, the approximate mass of the photon particle is 2.21 × 10-³² kg
