The colour of light which travels through glass with the minimum speed is?
The color of light that travels through glass with the minimum speed is violet. This is because the speed of light in any medium, including glass, is dependent on the medium's refractive index, with shorter wavelengths like violet experiencing a slower speed.
How does light passing through glass affect its speed and direction?
When light passes through glass, its speed decreases and it bends, or refracts, due to the change in the medium.
Is speed of violet light different from red light in glass?
Yes, the speed of violet light in glass is higher than the speed of red light. This is due to the phenomenon of dispersion, where different colors of light are refracted at different angles as they pass through a medium, causing them to travel at different speeds.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
How does the speed of light in glass compare to the speed of light in a vacuum?
It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.
What is the speed of sound travelling through glass?
It is approx 4540 metres/second
Which element can cut glass?
water can cut through glass but only when at a very high speed and a thin stream
Is it illegal to run amber triffic lights?
It is not illegal to run through amber traffic lights if they are the flashing amber lights. Amber lights that occur just before red lights are not illegal to run through, but caution should be observed. A sudden burst of speed to get through the light could cause an accident.
Will sound travel faster through Aluminium or glass?
Sound travels faster through aluminum than glass because aluminum has a higher speed of sound due to its higher stiffness and density compared to glass.
What happens to the speed of light when it travels from air into glass?
The speed of light decreases when it travels from air into glass because the glass has a higher refractive index than air. This causes the light to slow down as it moves through the denser medium.
What happened when a ray of light is shone at a glass block?
It all depends on the angle if incidence. In general the light will refract i.e. bend through the glass and come out at the other end. Also, the speed of light will vary through the glass.
What happens when light passes through a glass block?
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
