Explanation:
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.
Deserts has a very dry and hot climate, this may increase the water loss of plants through the leaves. Therefore, to prevent large amount of water loss in cactus, their leaves are modified to spines to reduce the surface area. In addition, the thick photosynthetic stems can help absorb and store more water, which is the necessary element for living things.
