Which characteristic accounts for the fact that red lights are used in dark rooms and DO NOT expose negatives during developing?
2 answers:
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
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

The acceleration of the particle at time t is:
The velocity of the particle at time t is given by the integral of the acceleration a(t):
and the position of the particle at time t is given by the integral of the velocity v(t):
Assuming the particle starts from position x(0)=0 at t=0, the distance the particle covers in the first t=2 seconds can be found by substituting t=2 s in the equation of x(t):
