What is the frequency of light for which the wavelength is 7.1 × 102 nm?

Brilliant_brown [7]

Answer:

Frequency, $f=4.22\times 10^{14}\ Hz$

Explanation:

Given that,

Wavelength of the light,

$\lambda=7.1\times 10^2\ nm=7.1\times 10^2\times 10^{-9}\ m\\\\\lambda=7.1\times 10^{-7}\ m$

We need to find the frequency of light. We know that light is an electromagnetic wave. It moves with the speed of light. So,

$c=f\lambda$

f is the frequency of light

$f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8\ m/s}{7.1\times 10^{-7}\ m}\\\\f=4.22\times 10^{14}\ Hz$

So, the frequency of light is $4.22\times 10^{14}\ Hz$ . Hence, this is the required solution.

The electric field in a region of space has the components Ey = Ez = 0 and Ex = (4.00 N/C · m) x. Point A is on the y axis at y

igor_vitrenko [27]

Answer:

$V_{b}-V_{a} = -38.72$

Explanation:

Consider the axis diagram attached.

Given:

Ey = Ez = 0

Eₓ = - 4x N/C · m

Since electric field is in x direction, potential difference would be:

$V_{b} - V_{a} =-\int\limits^{4.40}_{0} {E_{x} } \, dx$

Here we integrate between limits 0 and 4.40 which is distance between A and B along x-axis.

$V_{b} - V_{a} = -4 \left[\begin{array}{ccc}\frac{x^{2} }{2} \end{array}\right]^{4.40}_{0}$

$V_{b}-V_{a} = -4 (9.68)\\V_{b}-V_{a} = -38.72$
