Light always travels in a straight line with respect to space-time. If it appears to the observer that the light beam has bent it can only be concluded that space-time is bent.
Sound does not travel faster than light. The speed of light is 299,792,458 meters per second The speed of sound is 343.14 meters per second or, light travels at 186,000 miles per second sound at 751 MPH
Light is a form of radiation. Radiation is an emanation of energy from a body, that can pass through a vacuum unaffected. it travels in a straight line, and is only slightly affected by gravity. A black hole obviously will, with its massive gravity well, affect all forms of light and radiation. Heat, light particles (photons) and radiation particles (alpha, beta, and gamma) are all forms of radiation, among other more exotic forms.
Generally visible light and/or ultra-violet.
Group velocity in a waveguide is speed at which EM energy travels in the guide.It will always be less then speed light.
radio waves travels at the speed of light i,e 299,792,458 meters
Straight. Gravity bends light. It can act like a lens
Most often, the light travels in a straight line.But when it passes nearby a body having a large gravitational force, the path of the light bends or curves.

When light is Refracted it bends when it travels from one medium to another
Refraction
Light travels in straight lines when the medium's density is constant. When light enters a different density perpendicularly, it also travels in a straight line. When light enters a higher density at an angle, it bends towards an imaginary line perpendicular to its pont of entry. When light enters a lower density medium, it bends away from the imaginary perpendicular line. This is seen with objects partially submerged in water. The light exits the water and bends away from its normal path, making the object appear crooked in relation to the unsubmerged portion. Sometimes light will be reflected at the boundary of two mediums. This is seen in optic fibres.
When there's no gravity, light just travels in one direction at the speed of light. Gravity bends the direction at which light travels.
Yes because, Light travels in a straight path called a light ray.
Light bends, when it light travels at different speeds in different mediums. Hope that helps.
light travels in straight paths called rays
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
It does not, it travels as a wave
