What else can I help you with?
What do prisms drops of water and lenses all cause light waves to do?
They all cause light waves to bend or refract, due to the change in medium. This bending is a result of the change in the speed of light as it enters the material at an angle.
In which situation would the angle of refraction bend toward the normal?
The angle of refraction bends toward the normal when light travels from a less dense medium to a more dense medium, like from air to glass. This happens because the speed of light is slower in the denser medium, causing the light waves to refract towards the normal line.
Why Even though the phone is ringing no sound comes out of the jar what does this tell you about what is in the char what does the same experiment tell you about light waves?
The lack of sound coming out of the jar when the phone is ringing suggests that the jar is likely filled with a material that absorbs or blocks sound waves, such as a dense material like foam or cotton. This demonstrates how different materials interact with sound waves. Similarly, if light waves are blocked or absorbed in a similar experiment involving light passing into the jar, it would suggest that the jar is filled with a material that prevents light transmission, such as an opaque material like paper or cardboard.
Does lead block radio waves?
Yes, lead can block radio waves because it is a dense material that can absorb and reflect electromagnetic radiation, including radio waves.
What happens to the light waves during absorption?
During absorption, light waves transfer their energy to the absorbing material, causing the electrons in the material to move to higher energy levels. This leads to an increase in the internal energy of the absorbing material.
How do different materials affect light and sound waves?
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
How do the light waves coming from the pencil change speeds?
When light waves enter a material like glass or water, they slow down due to interactions with the atoms in the material. This change in speed is related to the optical density of the material, causing the light waves to bend, i.e., refract. Once the light waves exit the material, they resume their original speed in the air.
Where do the light waves change speed from a pencil?
Light waves change speed when they travel from air into the material of the pencil, and then change speed again when they exit the pencil back into the air. This change in speed causes the light waves to refract or bend.

How is optical density related to refraction?
As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)
Why can radio waves pass through walls but light cannot?
Radio waves are longer on the electromagnetic spectrum and can penetrate objects because they are less dense. Visible light and infrared light are shorter and therefore too dense to pass through objects.
Does an opaque material scatter light waves as they pass through it?
Yes, an opaque material does not allow light to pass through it and instead reflects or absorbs the light waves. This prevents the light waves from passing through the material and they are scattered in different directions.
Does lead block radio waves?
Yes, lead can block radio waves because it is a dense material that can absorb and reflect electromagnetic radiation, including radio waves.
Is rockwool a good material for soundproofing?
Yes, rockwool is a good material for soundproofing due to its dense and fibrous composition that effectively absorbs sound waves.
What happens to the light waves during absorption?
During absorption, light waves transfer their energy to the absorbing material, causing the electrons in the material to move to higher energy levels. This leads to an increase in the internal energy of the absorbing material.
