Light and other electromagnetic waves do indeed travel as a wave. For that reason, light, radio waves and all other electromagnetic waves can be characterized by a wavelength. Different colors of light have different wavelengths in the range of around 400 nanometers to 800 nanometers.
However, they can also be considered to be particles instead of waves. In some branches of physics, the concept of light as a particle can be very useful. For most of us, treating light as a wave is quite sufficient.

Is it correct to say that in every case any radio wave travels faster than any sound wave?
Yes. Radio is a form of electromagnetic wave, so it travels at the speed of light. Since sound requires a physical medium and it is (theoretically) impossible for matter to attain the speed of light, the speed of sound can never be equal to/above the speed of light, and this statement is correct.
Which type of wave travels faster gamma or radio?
The same. Both are electromagnetic waves; in a vacuum, they both travel at the speed of light.
One end of a horizontal string is caused to oscillate vertically while the other end is attached to a fixed object the wave that travels along the string is an example of?
a longitudinal wave
If one of the waves represents infrared light and one wave represents visible light which wave represents visible light?
Without any other information, the one with a shorter wavelength/higher frequency will be visible light.
Which wave represents visible light?
Visible light is a type of electromagnetic wave.
Why do light travels in straight line?
It does not, it travels as a wave
What kind of light travels in a straight line?
All light travels as a wave
What travels in a straight line and travels the fastest?
Light the electromagnetic wave.
The light from Polaris travels through space in the form of?
Light travels as light energy. Light is a type of electromagnetic wave.
Light travels as a longitudal wave?
No, light is a transverse wave.No, light is a transverse wave.No, light is a transverse wave.No, light is a transverse wave.
The light from Polaris travels through space in what form of energy?
Light travels as light energy. Light is a type of electromagnetic wave.
The wave crest of light waves are to the direction the wave travels?
Perpendicular. Light wave moves forward, the crests move at right angles to the wave
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
What kind of wave does light travel in?
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
What does light travel in?
The simplest answer is that light consists of particles with wave properties. Elementary particles also have wave properties. This is how light travels.
A disturbance that travels through a medium as a longitudinal wave?
Light does that.
Why do light rays travel in straight lines?
It does not, it travels as a wave
