The wavelength of yellow sodium light in vacuum is approximately 6.0 x 10-7m. The frequency
is most nearly:
a.
1.7 * 106 Hz
c.
1.8 * 102 Hz
e.
5.0 * 1014 Hz
b.
1.8 Hz
d.
2.0 x 10-15 Hz

The frequency of sodium light in vacuum is 5 × Hz.

Option e

Explanation:

It is known that frequency of a wave is inversely proportional to the wavelength of the wave. And the proportionality constant is the speed of light in vacuum. As the speed of light in vacuum is known as 3× m/s and the wavelength of the light in vacuum is given as 6 × m, then the frequency of the light is determined as

Frequency = Speed of light in vacuum/Wavelength of light

Frequency =

Frequency = 0.5× = 5 × Hz.

So the frequency of sodium light in vacuum is 5 × Hz.

d) physical means can be used to separate the components of air.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
