If the speed of light was the same in all materials would a lens cause light rays to bend?

No. Without refraction at a boundary between media with different refractive indices,
lenses wouldn't work. The only way we would have of forming real images would be
with curved mirrors.

∙ 13y agoWhen light passes through a boundary from one medium to another medium, the light may bend due to a phenomenon called refraction. The amount the light bends depends upon the angle of incidence of the light upon the boundary layer and the relative difference between the refractive index of the two media.
.
The amount by which light changes velocity depends upon the ratio of refractive indexes of the two media. This ratio, coupled with the angle of incidence, determines by how much light will be bent through refraction.

What problems would be caused by a lack of light?
A lack of light from the sun would cause an immediate cooling effect. For example, a nuclear winter occurs when the cloud of debris blocks the sun.
Do light rays travel quicker through water or air?
My take on it would be that Light would travel faster through water. Alcohol tends to be slightly more viscous. Remember that all things would have to be equal, temperature, pressure of air, the amount of air in the liquid, angle of light, etc. And (I'm guessing here) the difference would minimal. ========================================= Humm..... not sure that the reasoning above is correct. The speed of light in a vacuum is constant (c) and the fastest light can travel. When light passes through matter it slows and to know how much you really need to know the index of refraction and temperature of the substance it is passing through. The index of refraction of water is about 1.33, so the speed of light in water is (c/1.33). The index of refraction of Ethanol is 1.36 so the speed of light in Ethanol is (c/1.36). This light moves slower in Ethanol than water if both are at the same temperature.
Is it possible to travel back to the past if we travel at the speed of light?
Yes, it is possible for sub-atomic particles to travel faster than the speed of light (186,000 miles/second). A total of 15,000 neutrino beams were fired from Geneva, Switzerland --> Gran Sasso, Italy and were found to arrive about 60 nanoseconds faster than light would have. "It is a tiny difference," one scientist was quoted as saying, "But conceptually it's incredibly important." For more information on breaking the speed-of-light barrier, please see the article attached below.
Why do you think a light stick would be good light source around flammable materials?
It doesn't produce any heat, and heat is needed to explode anything. Therefore it takes away the possibility of any "accidental" explosions.
How many Years to reach the centre star of Orions belt at light speed?
To answer this question you must take into account the effects of relativity. All stars of orions belt are 1500 light years away, ie 1.42 x 1019 m. According to Newtonian physics it would take 1.42 x 1019 \ c = 4.7 x 1010s = 1500 years, where c is the speed of light. Now this is not true according to Einsteinian physics. according to Einsteinian physics as an object gains velocity its mass increases exponentially towards infinity as velocity approaches c. It is therefore impossible to travel at the speed of light as you would require more and more energy to accerate at a constant rate to c. In fact you would require infinite amounts of energy to reach c. You would also have infinite mass and this would do who knows what to the universe or space-time-continuum. in short this was probably a trick question, it is impossible. Maybe the question needs to be asked again but with a different speed, say 0.95c.
If your vehicle speed sensor is going out would that cause your check engine light to come on?
It could
What if traveling in your car at the speed of light and turn on your headlights?
head lights would be the least of ur worries if u had a car that could travel at the speed of light cause u wouldn't have a car cause it would turn to energy. -foxtrot3092- !!!END OF STORY!!!
Will you ever be able to travel at the speed of light?
probably not... at least not with our current technology traveling at the speed of light could also cause problems, everyone would be creating sonic booms....
Would Light protons stop you if you were going at the speed of light?
No - you would be stopped BEFORE you reach the speed of light, by your increasing mass (among other things). As your speed approaches the speed of light, your mass would approach infinity, and it would require an infinite energy to actually achieve the speed of light.Note that the "speed of light" is not really about light. It is a speed limit of our Universe; some have described it as the "speed of causality".
Is speed of light and speed of sound different in different materials?
yesthe speed of light in a vacuum is different than the speed of light in our atmosphere or another planets atmospherethe speed of sound is also different in the air than when it goes through a solid or liquidAddional answerThe first answer above not quite correct. The speed of light is the same regardless of what it passes through. It's 186,282 miles per second, but there is a small change due to the refractive index of different materials. But this difference is much less than the difference of the speed of sound in different materialsIf we go even further, it's the same to all observers (as Einstein would say). That means that even if you were travelling at close to the speed of light, it would appear to be travelling past or towards you at the speed of light. Now we're into relativity!
Would a faulty speed sensor on a 1999 Dodge Durango cause the ABS light to come on?
Yes it could.
Causes for the abs light being on?
Most common cause would be a faulty wheel speed sensor or damaged wires.
What would happen if two spaceships travelling in opposite directions at the speed of light ran straight into each other?
it would cause a explosion and everyone would die
Why traveling at the speed of light would we disperse?
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
How would you measure the speed of light?
Light years
If you travel at the speed of light in a car and turn your headlights 'ON' What will Happen?
To travel at the speed of light you would have to BE light so i guess you would became an even brighter light The switch to turn on the lights will work but no light will come on as you are already at that speed
How far back in time would you go if you traveled the speed of light?
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
