To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.

The equation that meets these parameters is given by

$\lambda = \frac{c}{f}$

Where,

c = Speed of light

$\lambda = Wavelength$

f = Frequency

Our values are given as

$c = 3*10^8m/s \rightarrow$ velocity of light in free space

f = 2Hz

Replacing we have that

$\lambda = \frac{c}{f}\\\lambda = \frac{3*10^8}{2}\\\lambda = 1.5*10^8m$

Therefore the correct answer is B.

Describe the difference between potential and kinetic energy

chubhunter [2.5K]

Answer:

Explanation:

Kinetic energy involves motion so something that is not moving has zero kinetic energy.

Potential energy does not involve motion and is based on position in a field like gravity and magnetic.

A copper cylinder is initially at 21.1 ∘C . At what temperature will its volume be 0.163 % larger than it is at 21.1 ∘C?

fomenos

To solve this problem we will apply the concepts related to the final volume of a body after undergoing a thermal expansion. To determine the temperature, we will use the given relationship as well as the theoretical value of the volumetric coefficient of thermal expansion of copper. This is, for example to the initial volume defined as $V_1$ , the relation with the final volume as
