Do Light waves travel more slowly through air and water?
Light waves travel faster through air than through water because air has a lower refractive index than water. This means that light waves experience less bending (refraction) in air compared to water, allowing them to move faster.
How do waves move without a medium?
Waves can move without a medium through electromagnetic radiation, such as light and radio waves, which can travel through a vacuum. These waves do not require a material medium like air or water to propagate.
Where do the light waves coming from the pencil change speed?
The light waves coming from the pencil change speed when they move from air (faster speed) to the glass or water (slower speed). This change in speed causes the light waves to refract or bend.
What does the word medium refer to in terms of lights and waves?
actually light is nothing but combination of so many Waves. so we can say that light and waves are not different things that means if a light can move through a medium we an say that the waves an also move through that so medium refers the same meaning both in terms of light and waves
Is this true Light waves do not change speed as they travel from air through water?
Light waves do change speed as they travel from air to water due to the change in the medium's refractive index. In general, light travels slower in water compared to air, causing a change in speed and resulting in the bending of the light waves known as refraction.

How does light waves compare with sound waves?
Light waves are electromagnetic waves that move at the speed of light. Sound waves are compression waves that move through a medium (air, liquids, solids), with varying speeds according to the medium.
Can light waves travel better in water or air?
Since air has a lower optical density than water, light waves can travel faster in air.

How do light waves affect matter?
light waves travel through a matter, such as air water and others
Which travels sound or light?
Both light and sound travel. Light travels the fastest.
Do waves move faster in air or in water?
Waves generally move faster in water compared to air. This is because water is denser and provides more resistance to the movement of the wave, which results in faster propagation speeds. In contrast, air is less dense and offers less resistance, causing waves to move slower.

What are similarities and differences between a sound waves and water waves in terms of medium?
Similarities: Both sound waves and water waves require a medium (air for sound waves, water for water waves) to propagate. They both travel in a wave-like motion, transferring energy without the physical movement of the medium. Differences: Sound waves are longitudinal waves that move through compression and rarefaction of molecules in the medium, while water waves are transverse waves that move through the oscillation of water particles. Sound waves propagate through air or solids, while water waves propagate through liquids.
What is the difference between the nature of water wave and a sound wave?
Water waves are mechanical waves that require a medium (water) to travel through, while sound waves are mechanical waves that can travel through different mediums such as air, water, or solids. Water waves are transverse waves, where the particles move perpendicular to the direction of the wave, while sound waves are longitudinal waves, where the particles move parallel to the direction of the wave.
