A substance is known to reflect red and blue light. What color would it have when it is illuminated by green light?

oksian1 [2.3K]

Answer:

A substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.

Explanation:

In visible light spectrum, a combination of red light and blue light gives magenta. Also a combination of red and green lights gives yellow light. and when green and blue lights mix the resulting light color is cyan.

However, if these three primary colors mix in equal proportion, we will have a neural color or white color and in the absence of these primary colors we will have black.

Thus, a substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.

Two long parallel wires carry currents of 20 A and 5.0 A in opposite directions. The wires are separated by 0.20 m. What is the

zzz [600]

The magnetic field midway between the two wires is $5.0*10^{-7} T$ .

It is given that Two long parallel wires carry currents of 20 A and 5.0 A in opposite directions. The wires are separated by 0.20 m.

We need to determine the magnetic field midway between the two wires.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

Magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge.

B=B1+B2

= $\frac{4\pi *10^{-7}*20 }{2\pi R1} +\frac{4\pi *10^{-7}*5 }{2\pi R2}$
