How can you compare speed of light to speed of sound when both of them are completely different while you have to visualise light and hear the sound?

It is the speed you are comparing, not the visualization.
-----
The classic way of understanding this involves our experience of lighting and thunder. When you see lightning in the far distance it takes a short time for the thunder produced to reach your ears.

How do speed of different forms of light compare?
How many different forms of light do you have ? ? The speed of all wavelengths of electromagnetic radiation is the same, at least in vacuum.
when opposite means completely different why do objects not have opposites?
Opposite doesn't mean completely different, it means the antithesis of. Dark is the opposite of light. It isn't merely different from light, it is defined as the absence of light. The word "dark" literally means, "not light." The moon is completely different from a frog, but they're not really opposites of each other. The moon is not a frog, granted, but it isn't defined by being not a frog. Its definition has no relationship to a frog, so it isn't the opposite of a frog. Likewise, its definition has no relationship to light or dark, which is why it isn't the opposite of those things, despite being completely different from them too.
Is sound wave a kind of light?
No. Sound is a completely and totally different phenomenon from light. Other things that are very much like light are . . . Radio signals Heat from the sun "UV" (ultraviolet) X-rays Gamma rays from space Sound is a completely different animal.
When you Visualise your reflection in glass bowl which is filled with waterwhat does it mean?
you are visualizing your face in the water Improved Answer: That's water's nature, which reflects anything if there is light.
Hor are LEDs similar to incandescent light bulb?
They emit light and the use electricity. Apart from that, they have little in common, the way they work is completely different.
Where does the light come from when you dream or internally visualise something?
The "light" in your dreams or visualization only exists in your imagination. There is no actual physical source of illumination and there is no activation of your eyes or optical nerves. Rather, your brain actively imagines and remembers the sensation of light.
How does the speed of light compare with the speed of gamma rays when both speeds are measured in a vacuum?
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
Why are lasers different from other kinds of light?
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.
Compare the sources of the beam in light microscope and electron microscopes?
Sample illumination is achieved in different ways in a light and electron microscope.In a light microscope, the sample is illuminates with light (photon energy)In an electron microscope, the sample is illuminated by a beam of electrons.Devon
What is the difference between an LED light and a fluorescent light?
It would actually be easier to list the similarities between them: They both convert electricity into visible light. That's pretty much it. Everything else about them is completely different.
How the speed of visible light compare with gamma rays when both speeds are measured in a vacuum?
Visible light and gamma rays are different parts of the full spectrum of light. Since they are really both just light, they travel at the same speed, the speed of light. 186,000 miles per second.
What is the difference between potential energy and light energy?
They are two completely different things. Light energy is electromagnetic waves. (EM). Potential energy is the energy stored within matter.
