Question

Interference effects always involve the propagation of one single wave.

True

False

The Retina is at the back of the eye and represents the detector of light rays.

True

False

Diffraction occurs when the light rays bend near the edge of an object.

True

False

A material is Transparent when light waves crossing them have a strong interaction with the atoms.

True

False

Blind Spots are three or four places of the Retina unable to detect light rays.

True

False

Light is an Electromagnetic Wave. They were discovered by:

		Isaac Newton
		Michael Faraday
		James Clerk Maxwell
		None of the above

During a total solar eclipse the Sun becomes black at certain spots on the Earth where the Moon shadow is found.

True

False

Answer 1

1) False

Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency.

2) True

The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens

3) True

Diffraction is the slight bending of light as it passes around the edge of an object. The amount ofbending depends on the relative size of the wavelength of light to the size of the opening

4) False

photons move inside glass or any transparent materials without interacting with the atoms

5)   True

6) James Clerk Maxwell

7) True

Duringa total eclipse of the Sun, night falls at noon as the Moon's dark shadow (or umbra) moves from west to east across the Earth.
