Answer:

calculated the speed of light over a short distance

Explanation:

Albert Michelson was an American physicist who conducted an experiment regarding the speed of light in the air 1880s. He believed in the existence of "aether," a field of space that is deemed necessary for transporting electromagnetic forces. In order to do this, he setup a device in order to accurately measure the speed of light in in aether. His device is now known as "Michelson interferometer." The result was actually negative. 

In order to make his experiment even more accurate, he collaborated with Edward Morley, a famous American scientist. Although the result failed, together, they were able to improve and come with the a standard length of light. This calculated the speed of light over a short distance, which was the significant result of Michelson's experiment.

Thus, this explains the answer.

How many 1140 nm long molecules would you have to line up end to end to stretch a distance of 158 miles?

dezoksy [38]

Answer:

221754385964.9123

Explanation:

Convert miles to nanometer

1 mile = 1.6 km

1 km = 1×10³×10³×10³×10³ nm

1 mile = 1.6×10¹² nm

So,

158 miles = 158×1.6×10¹² = 252.8×10¹² nm

Length of each molecule = 1140 nm

Number of molecules = Total length / Length of each molecule

$\text{Number of molecules}=\frac{252.8\times 10^{12}}{1140}\\\Rightarrow \text{Number of molecules}=221754385964.9123$

There are 221754385964.9123 number of molecules in a stretch of 158 miles

Microwave ovens emit microwave energy with a wavelength of 13.0 cm. what is the energy of exactly one photon of this microwave r

zysi [14]

First, let's calculate the frequency of this radiation, which is given by:
$f= \frac{c}{\lambda}$
where c is the speed of light and $\lambda$ is the photon wavelength. For this radiation, photons have wavelength of
$\lambda=13.0 cm=0.13 m$
Therefore their frequency is
$f= \frac{c}{\lambda}= \frac{3 \cdot 10^8 m/s}{0.13 m}=2.3\cdot 10^9 Hz$

The energy of a photon with frequency f is given by
$E=hf$
where h is the Planck constant. By using the frequency we found before, we find the energy of a single photon of this radiation:
$E=hf=(6.6 \cdot 10^{-34} Js)(2.3 \cdot 10^9 Hz)=1.52 \cdot 10^{-24} J$
