Respuesta :
the frequency of each wavelength of electromagnetic radiation is
A)frequency of wavelength 632.8nm(red light from helium–neon laser)
is 4.738×10¹⁴ s⁻¹
B)frequency of wavelength 503 nm (maximum solar radiation)
is5.960×10¹⁴ s⁻¹
C)frequency of wavelength 0.052nm (medical x-rays)
is5.765×10¹⁸s⁻¹
A)
632.8 nm (wavelength of red light from helium–neon laser)
1 nm = 10⁻⁹ m
632.8 nm = 632.8×10⁻⁹ m = 6.328×10⁻⁷ m
The speed of light is c = 2.998×10⁸ m/s
λ = 6.328×10⁻⁷ m
the frequency can be calculated as
ƒ = c / λ
ƒ = (2.998×10⁸m/s) / (6.328×10⁻⁷ m)
ƒ = 4.738×10¹⁴ s⁻¹
frequency of wavelength 632.8nm is 4.738×10¹⁴ s⁻¹
B)
503 nm (wavelength of maximum solar radiation)
1 nm = 10⁻⁹ m
503 nm = 503×10⁻⁹m = 5.03×10⁻⁷ m
c = 2.998×10⁸ m/s
λ = 5.03×10⁻⁷ m
the frequency can be calculated as;
ƒ = c / λ
ƒ = (2.998×10⁸ m/s) / (5.03×10⁻⁷m)
ƒ = 5.960×10¹⁴ s⁻¹
frequency of wavelength 503 nm is5.960×10¹⁴ s⁻¹
C)
0.052 nm (wavelength contained in medical x-rays)
1 nm = 10⁻⁹ m
0.0520 nm = 0.0520×10⁻⁹ m = 5.20×10⁻¹¹m
Where the speed of light is
c = 2.998×10⁸ m/s
λ = 5.20×10⁻¹¹ m
the frequency can be calculated as
ƒ = c / λ
ƒ = (2.998×10⁸ m/s) / (5.20×10⁻¹¹ m)
ƒ = 5.765×10¹⁸s⁻¹
frequency of wavelength 0.052nm is5.765×10¹⁸s⁻¹
A)frequency of wavelength 632.8nm(red light from helium–neon laser)
is 4.738×10¹⁴ s⁻¹
B)frequency of wavelength 503 nm (maximum solar radiation)
is5.960×10¹⁴ s⁻¹
C)frequency of wavelength 0.052nm (medical x-rays)
is5.765×10¹⁸s⁻¹
