Question

URGENT!!

Answer 1

Answer: Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum.

Explanation: Photons reflected by pigments in leaves are used by leaves to carry out photosynthesis is not true as the photons are absorbed as a source of energy by the pigments to carry out the process of photosynthesis.

Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum is true as only visible light is visible to human beings.

Photons are units of light that travel from the sun to leaves in the same way that particles travel through space is not true as photons travel from the sun to leaves by radiation in the form of electromagnetic waves and do not require any medium but particles require medium to travel.

The wavelengths that make up the electromagnetic spectrum each have the same amount of energy is not true as the electromagnetic radiations have different wavelengths and thus have different energies.

$E=\frac{hc}{\lambda}$

Answer 2

Human beings can only see a small fraction of the wavelengths that make up the electromagnetic spectrum. ;)
