are you sure
I apologize for the mistake in my previous response. The correct answer is:
True
True
what is the real answer
The correct answer is True.
Cones detect light and are responsible for detecting color vision. There are three types of cones that detect different wavelengths of light - red, green, and blue.
Rods are responsible for detecting dim light and are not involved in color vision.
The brain combines the signals from the cones to interpret and perceive color.

The energy of an electromagnetic wave is directly proportional to its frequency. Since energy = Planck's constant x frequency, the higher the frequency, the higher the energy.
From the given table, Wave D has the highest frequency (highest value in the frequency column), and therefore, Wave D has the GREATEST amount of energy.
From the given table, Wave D has the highest frequency (highest value in the frequency column), and therefore, Wave D has the GREATEST amount of energy.
