When a ray of white light strikes an object, its color depends on how it interacts with the surface. If all the colors of light are reflected equally, the object will appear white to our eyes. This occurs because white light is made up of all the colors in the visible spectrum (red, orange, yellow, green, blue, indigo, violet). When all of these colors are reflected, they combine to create white light.

Option 1: Black

If all the colors of light are absorbed by the surface, none of them will be reflected back and the object will appear black. Black objects absorb all colors of light and do not reflect any.

Option 2: White (Correct Answer)

If all the colors of light are reflected by the surface, the object will appear white. White objects reflect all colors of light equally and do not absorb any.

Option 3: Grey

Grey is a mixture of black and white. If the surface reflects some colors of light while absorbing others, the object may appear grey.

Option 4: Opaque

The term "opaque" refers to an object that does not allow light to pass through it. It is not directly related to the appearance of the object. Depending on the colors reflected or absorbed by an opaque object
