Question

What kind of electromagnetic radiation can honeybees see but not the humans?
A) Infrared radiations
B) Ultraviolet radiations
C) Visible radiations
D) None of the above

Answer 1

We have to remember that the order of wavelength is highest for radio waves in the electromagnetic spectrum. Ultraviolet radiation has a moderate value of wavelength i.e. $100 - 400nm$ whereas for the visible region it is $400 - 700nm$ and for infrared radiations it is followed by $700 - 2000nm$.

Complete answer:
We have to remember that the honeybees can see ultraviolet radiations which have a wavelength of $100 - 400$nm whereas humans can see from a wavelength of $400 - 700nm$. Humans cannot see ultraviolet radiations. Bees can differentiate between the dark and light colors therefore they can easily see red color. The color of rainbow can be easily seen by the eyes of humans. The representation of colors in rainbow is as follows: VIBGYOR which says violet, indigo, blue, green, yellow, orange and red. Red color has maximum wavelength and has lowest energy or frequency whereas violet has shorter wavelength and has maximum energy.
The order of wavelength is highest for radio waves in the electromagnetic spectrum. Ultraviolet radiations can be seen by bees since they have a moderate value of wavelength, but humans cannot see these radiations.
Option A) this is an incorrect option as infrared radiation has a wavelength of $700 - 2000nm$ which cannot be seen by either bees or humans.
Option B) This is a correct option as bees can see ultraviolet radiation having wavelength $100 - 400nm$ , it is easier for them to distinguish between dark and light colors but humans cannot see ultraviolet light.
Option C) this is an incorrect option as bees cannot see visible radiations but humans do. A human eye can see visible radiation because it is white light also it has a wavelength of $400 - 700nm$.
Option D) this is an incorrect option as we got option B as the correct answer.

Note:
We have to remember that the rainbow colors falls under the visible radiations that a human eye can see .The representation of colors in rainbow is as follows: VIBGYOR which says violet, indigo, blue, green, yellow, orange and red. Red color has maximum wavelength and has lowest energy or frequency whereas violet has shorter wavelength and has maximum energy.
