Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.

How does light refract?

it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.


Why can radio waves refract around buildings while light waves cannot?

that's easy .. you know that radio waves has very wide wave length ( 10^3 meter ) while light _ by which you mean visible light i guess _ has smaller wave lengths which ranges between ( 7000 and 4000 ) Angstrom (the angstrom is 10^-10 meter) also from the conditions diffraction is to pass by narrow slit .. and it depends on the ratio ( wave length of light / width of the object or slit )


How does a line of a marching band make a turn without getting out of step and how could this be related to the bending of light through a prism?

A marching band makes a turn by employing a technique called "pivoting," where the band members on the outside of the turn take larger steps while those on the inside take smaller steps. This allows the entire line to remain in sync and maintain formation. Similarly, the bending of light through a prism can be likened to this process, as different wavelengths of light refract at varying angles when entering and exiting the prism, creating a spectrum while still following the laws of refraction. Both phenomena demonstrate how coordinated movement around a pivot point can create orderly transitions, whether in marching formations or the behavior of light.


Why do stars not twinkle much in the winter?

Stars twinkle due to the Earth's atmosphere causing the light from stars to refract as it passes through different layers of varying density. In winter, the Earth's atmosphere is typically more stable and less turbulent, resulting in less twinkling of stars compared to other seasons. This stability reduces the amount of atmospheric distortion that causes the twinkling effect, leading to clearer and steadier views of stars in the winter sky.


What are the waves in the electomagnetic spectrum?

The speed of every electromagnetic wave is the same. That includes television waves, FM radio waves, heat waves, infrared light, green light, purple light and ultraviolet light waves, microwaves, x-rays, AM radio waves, bluetooth signals, taxi radio waves, garage- door-opener waves, and gamma ray waves ... because all of these waves are the same thing. Their speed is 299,792,458 meters per second, or 186,282 miles per second.
