Difference Between Conduction, Convection and Radiation:
While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.
So I would agree with C. Radiation can move through empty space, whereas conduction and convection require matter to transfer heat (by movement or direct contact).
<span>a) light is a form of matter less dense
than air
b) light travels in straight lines
c) light has different
colors
d) light has different intensities and can be dim or bright
Yes, thank you for coming back and supplying the list of choices.
At the level of Physics all the way up to somewhere in college, <em>choice-a)</em>
is not a property of light.

It's important to know that diffraction gratings can be identified by the number of lines they have per centimeter. Often, more lines per centimeter is more useful because the images separation is greater when this happens. That is, the distance between lines increases.
<h2>Therefore, the answer is 2.</h2>
Now none of these answers are really good a Table is best fit to show a wide range of data, while a graph is still used for the same purpose, its data is usually scattered, so a table is a neat and organized way to display a wide range of data.
