Luminous objects such as flashlights emit light that we can see. how do we see an object that isn’t luminous?
the object emits light that reaches our eyes.
light reflects off the object and reaches our eyes.
light passes through the object uninterrupted.
light is fully absorbed by the object.
we can’t see an object that isn’t luminous.

The correct answer is option B

The objects that allows the light to radiated from its body is called as luminous object. Whenever any light ray falls on any object it gets reflected back to the to the eyes of the observer. The light falls off the object that is not luminous and gets reflected back into the eyes of the observer. This makes the object visible to the people.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
