I don’t know but I will figur it out
The time to distance ratio is 2.1:1 , making the first time 5 seconds, the first distance 18.9 m, and the second time 15 seconds. I hope this helps!
Answer:
a) Wavelength .
Explanation:
Visible light is comprised of all the seven colors Violet , Indigo , Blue , Green , Yellow and Red .
Color depends up on the wave length of the light .
For example a red ball appears red because it absorbs wavelengths of all the other colors and reflects only wavelengths corresponding to red color.
Answer:
hange in value is because the observer and the source has a relatively high speed
Explanation:
The emission of a molecular with is always the same, the reason why they change in value is because the observer and the source has a relatively high speed.
As the energy of the beam varies inversely with the wavelength, this shift is due to the fact that the earth and the cloud are moving away from each other.
If we want to find the velocity eta value we must use the relativistic Doppler effect
f ’= fs √ [(1- v / c) / (1 + v / c)]
