The same.
No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
Radio and light waves are electromagnetic waves, sound waves are not.
Electromagnetic Waves all have constant velocity which are equal to the speed of light. It is only the frequency of the wave that differentiates ie between radio, gamma, X-ray. The velocity is always fixed at 3 x 10^8 ms^-1 which is equivalent to the speed of light.
radio telescope detects radio waves and a light telescope views light waves.
Light waves, radio waves, and microwaves are all on the electromagnetic spectrum.
In the field of physics, that rather depends on the frequency. Optics in the case of light waves; Acoustics in the case of audio (pressure/velocity) waves; radio-physics in the case of radio waves; and Geophysics in the case of seismic waves. I presume you do not inquire after Sting Rays.
does the color of a lease affect the velocity of the light waves projected by the laser?
Infrared light, microwaves and radio waves have wavelengths longer than visible light. Radio waves have the longest wavelength.
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
Radio waves have a far longer wavelength than visible light. The radio waves that do the cooking in your microwave oven are as long as roughly 310,000 waves of blue light placed end-to-end. The radio waves transmitted by an AM station at 1400kHz on your AM dial are roughly 550 billion times as long as blue-light waves.
Light waves are the wavelengths that register on our visual receptors. Radio waves have a much longer wavelength and not as much energy.
