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.
Answer:
Sound is a vibration, or wave, that travels through the air. Sound waves are invisible to our eyes; unless we find a way to make the sound waves move something that we can see. In this activity, your child will use different noise-making objects to cause sound waves and make sand visibly move.
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength.
Explanation:
When the vibrating air hits your eardrum, it causes your eardrum to vibrate, just as the balloon did. These vibrations are transferred through the tiny bones in your ear to the inner ear. These vibrations are detected by nerves, which send impulses that your brain "hears" as sound.
Answer: Geologists study rocks to find clues to Earth's formation. Evidence from rocks and fossils allows us to understand the evolution of life on Earth.
Subjective refers to something that takes place within the mind of the person. It is modified based on individual bias.
Objective refers to defining things or expressing them without any distortion. They are expressed only as perceived.
Finally, mineral is anything composed of matter apart from animals and plants.
