In science, Bob learns that the energy of a wave is directly proportional to the square of the waves amplitude. If the energy of

a wave is 4 J, what should he predict as the amplitude of the wave?

The energy of a wave is directly proportional to the square of the waves amplitude. Therefore, E = A² where A is the amplitude. This therefore means when the amplitude of a wave is doubled the energy will be quadrupled, when the amplitude is tripled the energy increases by a nine fold and so on.
Thus, in this case if the energy is 4J, then the amplitude will be  √4 = 2 .

The lasers are red, meaning that they are giving off light in the _____ region of the electromagnetic spectrum
Softa [21]

As per the question the color of laser light is given as red.

If we arrange all the electromagnetic waves in the decreasing order of frequency ,then the electromagnetic spectrum contains gamma ray as the first which is followed by all other electromagnetic waves according to their frequency.

The visible light ranges from 400 nm to 700 nm which contains sunlight i.e white colors with it's constituent colors starting from violet to red. The red color is the longest wavelength part of the visible region.

The wavelength of visible light is longer than ultraviolet wave but smaller than infrared radiation. Except the bisible region,the color of radiation is invisible to eye.


As per the question the color of emiited laser radiation is red .Hence it must lie in the visible region of the electromagnetic spectrum.
