<span>The answer for your question is
B. A warm air mass overtakes a cold one, and the warm air gradually rises and cools. The water in the air condenses to form clouds and gentle rain.</span>
Answer:
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
Explanation:
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
The speed of a wave c, its wavelength λ and frequency f are all related according to c=λf. So if c is the same for all EM waves, then if you (say) double the frequency of a wave, its wavelength will halve.
