The chart shows the speed at which light travels through different media.

A 2 column by 5 row table. Column 1 is titled Medium and contains the following entries: Water, Air, Glass, Diamond. Column 2 is titled Speed of Light (meters per second) and contains the following entries: 2.25 times 10 Superscript 8 baseline, 2.99 times 10 Superscript 8 baseline, 1.97 times 10 Superscript 8 baseline, 1.24 times 10 Superscript 8 baseline.
In which medium would light have the longest wavelength?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

a cold ice-tea.

pour in room temperature or cold water. cover the pitcher and refrigerate. steep white or green tea for 6 to 8 hours; steep black or oolong tea for 8 to 12 hours.jun 28, 2015
