Question

1. which statements are true about light? select all that apply.

light is a transverse wave.
light is the fastest traveler in the universe.
light can travel through empty space.
light requires a medium to travel.

Explanation:

• Light is a transverse wave as the oscillations of the electric and magnetic fields are perpendicular to the direction of wave propagation.
• Light travels at a speed of \(c = 3\times10^{8}\ m/s\) in vacuum and is the fastest traveler in the universe according to current scientific understanding.
• Light can travel through empty space (vacuum) as it does not require a material medium for its propagation.
• Light does not require a medium to travel. This is in contrast to mechanical waves (e.g., sound waves) which do require a medium.

Answer:

Light is a transverse wave, Light is the fastest traveler in the universe, Light can travel through empty space.
