What else can I help you with?
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
Is a frosted glass translucent?
A translucent object is something that you can see through, but not completely. When light hits a translucent object, the light is scattered, meaning only some of the light passed through. An opaque object (like metal or wood) allows no light to pass through, and a transparent object (like glass or air) allows all or most light to pass.
Can glass objects be made through the lost-wax process?
Glass objects can be made through the lost-wax process
What is the Difference between glass fibre and fibreglass?
glass you can see through and fibreglass you can not
Is glass transparent translucent or opaque?
No, such a transparent metal is not possible. Metals are a conductor of electricity. As a result of this, electromagnetic waves of the wavelength of light cannot penetrate it.
What can happen to light traveling through a glass filled with water?
Light traveling through a glass filled with water will experience refraction, causing it to change speed and direction. The change in speed is due to the difference in optical density between the glass, water, and air. The bending of light at the interface of water and glass is what causes the phenomenon of refraction.
What little girl passed through a looking glass?
Alice, who appeared in Lewis Carroll's books, Alice's Adventures in Wonderland and its sequel, Through the Looking Glass and what Alice Found There.
The traveling of concentrated light through long tiny fibers of glass to carry sound is called fiber?
"optics"
What is the traveling of concentrated light through long tiny fibers of glass to carry sound is called?
fiber-optic
Sunlight is slowed most when traveling through?
Sunlight is slowed the most when traveling through a medium with a high refractive index, such as glass or water. This is due to the increased interaction between the photons of light and the atoms in the medium, causing the light to bend and slow down.
What happens if light is passed through a glass slab whose sides are not parallel?
it becomes kinda prism
When sunlight is passed through a glass prism it breaks up into different colors when these colors are passed through a reverse prism they form white light this shows that?
sunlight contains all colors.
What happens when a yellow light is passed through a green glass prism?
When a yellow light is passed through a green glass prism, the prism will refract the light, separating it into its component colors. In this case, the green glass will only allow green and yellow wavelengths to pass through, causing the yellow light to refract at a different angle than green light.
What happens to light which does not go into the glass block?
Light that does not enter the glass block will either continue traveling through the air or be reflected off the surface of the glass block. The reflected light may create a reflection or be absorbed by the surroundings.
Why do the light pases without bending from center of curvature?
well if you try to send light through a curve glass it will bend except in the middle its because the middle of the glass is the focal point of the glass .the ray doesn't bend though the curve is a normal glass a concave mirror or a convex glass it appers the same from the other side
How does electromagnetic waves travel?
It depends on what they're traveling through. If they're traveling through vacuum, then it's what we call the "speed of light" but it's really the speed of all electromagnetic waves: 299,792,458 meters (186,282 miles) per second. If they're traveling through some material substance, such as air, water, glass, jello, etc., then the speed is a little less.
What does the path of the sunlight through the air have to do with the climates?
Light is affected by a force called refraction which diverts its path depending on the 'thicknesss' of the medium it is traveling through. For example, a ray of light traveling through air and entering a thicker medium like glass will be refracted and travel in a different direction when it enters the glass. Different climates will create different atmospheric conditions which will make the light travel in different directions.
