Which characteristic accounts for the fact that red lights are used in dark rooms and DO NOT expose negatives during developing? A) small size B) low energy C) high energy D) high velocity

Respuesta :

b) low energy, because red is on the far left of the electromagnetic spectrum.

Answer:

A) Low Energy

Explanation:

Red colour light is light with larger wavelength due to which it can travel large distance. Due to this property of red colour light we use this colour to show different signals so that they are visible from distance

Here we also know by the formula of energy

[tex]E = \frac{hc}{\lambda}[/tex]

here we can see that the wavelength of light and energy of light is inversely depends on each other

So here we can say that red colour light is of larger wavelength and smaller energy due to which it can travel larger distance

so correct answer is

A) Low Energy
