Calculate the frequencies corresponding to the wavelengths 500.00 nm and 500.10 nm. Use these to check the accuracy of equation
mel-nik [20]

Explanation:

It is given that,

Wavelength, \lambda_1=500\ nm=5\times 10^{-7}\ m

Wavelength, \lambda_2=500.10\ nm=5.001\times 10^{-7}\ m

We need to find the frequencies from corresponding wavelengths. The frequency of the light is given by :

f=\dfrac{c}{\lambda}  

c is the speed of light

Frequency 1,

f_1=\dfrac{c}{\lambda_1}  

f_1=\dfrac{3\times 10^8\ m/s}{5\times 10^{-7}\ m}  

f_1=6\times 10^{14}\ Hz

Frequency 2,

f_2=\dfrac{c}{\lambda_2}  

f_1=\dfrac{3\times 10^8\ m/s}{5.001\times 10^{-7}\ m}  

f_1=5.99\times 10^{14}\ Hz

Hence, this is the required solution.

Two point charges of equal magnitude are 7.3 cm apart. At the midpoint of the line connecting them, their combined electric fiel
Delicious77 [7]

Answer:

q₁ = q₂ = Q = 14.8 pC

Explanation:

Given that

q₁ = q₂ = Q = ?

Distance between charges = r =7.3 cm = 0.073 m

Combined electric field = E₁ + E₂ = E = 50 N/C

Using formula

E=2\frac{kQ}{r^2}

Rearranging for Q

Q= \frac{Er^2}{2k}\\\\Q=\frac{(50)(.005329)}{2\times 9\times 10^9}

Q=14.8\times 10^{-12}\, C\\\\Q=14.8\, pC
