Question

which of the following describes light as a wave?
light is a transverse wave.
light is a converse wave.
light must travel through a medium.
light is a wave but does not have frequency as a property.
question 14
of the terrestrial planets, earth and venus are which of the following?
different in density
about the same size
similar to gas planets
very different in size

Explanation:

• Light is an electromagnetic wave and electromagnetic waves are transverse waves. Transverse waves have oscillations perpendicular to the direction of wave propagation.
• There is no such thing as a "converse wave" in wave terminology.
• Light does not need a medium to travel (it can travel in a vacuum), while mechanical waves (like sound) need a medium.
• Light, as a wave, has properties like frequency, wavelength, amplitude etc.

• Among terrestrial planets (Mercury, Venus, Earth, Mars), Earth and Venus are often referred to as "sister planets" because they are about the same size. Venus has a diameter of about 12,104 km and Earth has a diameter of about 12,742 km.
• Their densities are relatively close (not "different in density" in a significant sense compared to other non - terrestrial planet comparisons).
• Terrestrial planets (rocky) are very different from gas planets (Jupiter, Saturn etc.).
• As mentioned, their sizes are not "very different".

Answer:

Light is a transverse wave.
about the same size
