<u>Mass</u>
- Mass is measured in kilograms.
- Mass does not change when gravity changes.
- Mass is the amount of matter in something.
<u>Weight</u>
- Before I answer, we have to know weight formula. Weight = mass × acceleration due to gravity.
- Therefore, weight is measured in Newtons.
- Weight changes when gravity changes. This is because weight is dependent on acceleration due to gravity.
- Weight is a gravitational force.
Hope you could understand.

Radio waves and visible light are both forms of electromagnetic radiation, so they both travel at the speed of light in vacuum. What makes them different are their wavelengths (or synonymously their frequencies).The wavelengths of visible light span from about 390-700 nm, and the frequency from 430 to 790 THz.The wavelengths of radio waves go from about 1 mm to 100 km, and frequencies between 3 kHz and 300 GHz.The different sized wavelengths also give rise to slightly different properties. For example, since radio waves have a longer wavelength and lower frequencies, they are less energetic than visible light. Recall:Elight=hν=hcλ
where Elight is the energy of the light, h is Planck's constant, c is the speed of light, νis the frequency of light, and λ is the wavelength
Answer: The visible part of the electromagnetic spectrum, <u>specifically blue and red wavelength</u>
Explanation:
Let's begin by explaining that pigments generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.
In this sense, in the thylakoid membranes there are two types of <u>chlorophyll pigments</u>:
-clorophyll b that absorbs the blue light of the electromagnetic spectrum
-clorophyll a that bsorbs the red light of the electromagnetic spectrum
That is why we generally see plants in green color and not in other colors.
