Answer:
![f = 0.01Hz](https://tex.z-dn.net/?f=f%20%3D%200.01Hz)
Explanation:
Given
![Wavelength = 3 * 10^{10}m](https://tex.z-dn.net/?f=Wavelength%20%3D%203%20%2A%2010%5E%7B10%7Dm)
Required
Determine the frequency of the light waves
Frequency is calculated using:
![c = fL](https://tex.z-dn.net/?f=c%20%3D%20fL)
Where
c = speed of light
and
![c = 2.998 * 10^8 m/s](https://tex.z-dn.net/?f=c%20%3D%202.998%20%2A%2010%5E8%20m%2Fs)
Make f the subject in:
![c = fL](https://tex.z-dn.net/?f=c%20%3D%20fL)
![f = \frac{c}{L}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7Bc%7D%7BL%7D)
Substitute values for c and L
![f = \frac{2.998 * 10^8}{3*10^{10}}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B2.998%20%2A%2010%5E8%7D%7B3%2A10%5E%7B10%7D%7D)
Apply law of indices
![f = \frac{2.998 * 10^{8-10}}{3}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B2.998%20%2A%2010%5E%7B8-10%7D%7D%7B3%7D)
![f = \frac{2.998}{3} * 10^{-2}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B2.998%7D%7B3%7D%20%2A%2010%5E%7B-2%7D)
![f = 0.9993 * 10^{-2}](https://tex.z-dn.net/?f=f%20%3D%200.9993%20%2A%2010%5E%7B-2%7D)
Approximate
![f = 1 * 10^{-2}](https://tex.z-dn.net/?f=f%20%3D%201%20%2A%2010%5E%7B-2%7D)
![f = 10^{-2}Hz](https://tex.z-dn.net/?f=f%20%3D%2010%5E%7B-2%7DHz)
or
![f = 0.01Hz](https://tex.z-dn.net/?f=f%20%3D%200.01Hz)

Answer: Becuse
Explanation:Most states require that all electoral votes go to the candidate who receives the most votes in that state.

Industrialization in the US made Americans consumers as hey would rely more and more on what was produced from this new method. Businesses grew, which helped the spread of industrialization to start. The opportunities to select and purchase from a larger variety of goods, would lead to the economic development of the country. The businesses, country, and citizens were in some ways consumers to industrialization in the late 19th century.
