Rank in order the following according to their speeds, from fastest to slowest: (i) 425-nm-wavelength light through a pane of glass, (ii) 500-nm-wavelength light through air, (iii) 540-nm-wavelength light through water, (iv) 670-nm-wavelength light through a diamond, and (v) 670-nm-wavelength light through a vacuum.

v > ii > iii > i > iv

Explanation:

The speed of light does not depend on the wavelength of light rather the medium through which it passes through.

v) The speed of light in a vacuum is maximum = 300000 km/s

ii) The speed of light in air = 2999910.026 km/s

iii) The speed of light in water = 2255639.097 km/s

i) The speed of light in glass = 1973684.210 km/s

iv) The speed of light in diamonds = 1239669.421 km/s

Hence the ranking will be

v > ii > iii > i > iv

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
