Answer:
b) False
Explanation:
in trapezoidal rule the error is proportional to and the order of accuracy is proportional to
.
Trapezoidal rule is numerical integration method .Trapezoidal rule is used to find the area of curves.In trapezoidal rule we finds the approximate value of integration.But the real value of integration will not differ to much from the value which finds by using trapezoidal rule.
Answer:
Frequency = 3.5294×10¹⁴ s⁻¹
Wavenumber = 1.1765×10⁶ m⁻¹
Energy = 2.3365x 10⁻¹⁹ J , 1.4579 eV , 2.3365x 10⁻¹² erg
Explanation:
Given the wavelength = 850 nm
1 nm = 10⁻⁹ m
So, wavelength is 850×10⁻⁹ m
The relation between frequency and wavelength is shown below as:
c = frequency × Wavelength
Where, c is the speed of light having value = 3×10⁸ m/s
So, Frequency is:
Frequency = c / Wavelength
Frequency = 3.5294×10¹⁴ s⁻¹
Wavenumber is the reciprocal of wavelength.
So,
Wavenumber = 1 / Wavelength = 1 / 850×10⁻⁹ m
Wavenumber = 1.1765×10⁶ m⁻¹
Also,
where, h is Plank's constant having value as 6.62x 10⁻³⁴ J.s
So,
Energy = 6.62x 10⁻³⁴ J.s × 3.5294×10¹⁴ s⁻¹
Energy = 2.3365x 10⁻¹⁹ J
Also,
1 J = 6.24×10¹⁸ eV
So,
Energy = 2.3365x 10⁻¹⁹ × 6.24×10¹⁸ eV
Energy = 1.4579 eV
Also,
1 J = 10⁷ erg
So,
Energy = 2.3365x 10⁻¹⁹ × 10⁷ erg
Energy = 2.3365x 10⁻¹² erg
