A student placed a glass jar over a ticking clock and observed that both the ticking sound and the clock were clearly audible and visible through the glass jar.
Next, the student covered the glass jar with a black paper sheet. The ticking of the clock could still be heard, though it was slightly muffled. The clock was not visible through the jar.
Choose the correct word for each blank to correctly complete the sentence, giving the reason for the observations made when the jar was covered with the black paper sheet.
Sound waves are (a) through opaque materials like paper, while light waves are (b) .
When something is (a) it means it is allowing no light to pass through
When something is (a) it means it is allowing some light to pass through.

The picture shows a duck swimming in a pond. Why does there appear to be another duck head in the water?
The water in the pond reflects light from the Sun, making a mirror image.
The molecules in the atmosphere refract the light, splitting it into two images.
The duck scatters the light, making hundreds of tiny refractions that collect into an image.
The bottom of the pond absorbs the light, then projects it toward the surface as an image.
The pencil appears to be broken under water because the water -
absorbs light
produces light
repels light
refracts light
Which explains why the fork looks different under water?
light is refracted at an angle
the wavelength of light lengthens
light cannot pass through the glass
the amount of light increases when going through water
