Light waves come in many different varieties, and can be seen as many different colors. What is the main difference between a light wave that produces the color blue and a light wave that produces the color red? A. wavelength B. amplitude C. direction D. magnitude

A. Wavelength

Explanation:

A wavelength is the distance between two successive crests or troughs of a wave.

The difference between blue light and red light is just that the rays of red light have longer wavelength than that of blue light.

Due to this, blue light has a higher frequency than red light. This is because wavelength and frequency are inversely proportional (the higher the wavelength, the lower the frequency).

c = λ * f

Where  λ = wavelength, c = speed of light, f = frequency

Hence, blue light has more energy than red light, because energy is directly proportional to frequency (the higher the frequency, the higher the energy)

Where h = Plancks constant

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
