Aims: To derive an expression for the wavelength/frequency of Hawking radiation emitted by non-spinning black holes in terms of the radius of event horizon (λ=8πR_s & v= c/8πR_s) using quantum theory of radiation (E= hv) energy of Hawking radiation and the radius of event horizon of non-spinning black holes (R_s =2GM/c²), which may be regarded as the characteristics of non-spinning black holes.
Study Design: Data for the frequencies and wavelengths of Hawking radiation emitted from black holes have been calculated with the help of rest masses for stellar – mass black holes (M ~ 5 ­ 20 M_ʘ) in X-ray binaries and for the super massive black holes (M ~ 10⁶ – 10^9.5 M_ʘ) in active galactic nuclei using λ=8πR_s & v= c/8πR_s which corresponds to the research work entitled: Frequency of Hawking radiation from black holes by Mahto et al. in International Journal of Astrophysics and Space Science (Dec. 2013).
Place and Duration of Study: Department of Physics, Marwari College under University Department of Physics, T.M.B.U. Bhagalpur between January 2014 and June 2014.
Methodology: It is completely theoretical based work using Laptop done at Marwari College Bhagalpur and the residential research chamber of the first author.
Results: The astrophysical objects emitting the radiations of frequencies (8.092x10²Hz to 2.023x10²Hz) or wavelengths (3.707x10⁵m to 14.828x10⁵m) in X-ray binaries and frequencies (4.046×10^-3Hz to 0.809×10^-6Hz) or wavelengths (7.414×10¹⁰m to 37.070×10¹³m) in active galactic nuclei may be classified as non-spinning black holes.
Conclusion: The frequencies or wavelengths of Hawking radiation emitted from non-spinning black holes may be regarded as the characteristics of black holes in addition to the mass, spin and charge.
