Why do longer wavelengths travel further than short wavelengths?

Longer waves are diffracted by the earth atmosphere and so can cling to the surface of the earth , whereas shorter waves just goes out into space because they are easily absorbed by the molecules in the air.

What is the reason for violet light to bend more than the red light?

Each beam of light, with its own particular wavelength (or color), is slowed differently by the glass. Since violet light has a shorter wavelength, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while red light is bent the least.

Why does light bend when it travels from one medium to another?

When a ray of light travels from one medium to another, its speed changes and this change in speed of light causes a part of wave to travel slower than the other part. Thus, bending of light takes place in refraction.

Why do longer wavelengths penetrate more?

Light with longer wavelengths is absorbed more quickly than that with shorter wavelengths. Because of this, the higher energy light with short wavelengths, such as blue, is able to penetrate more deeply.

Why shorter wavelengths have more energy?

The energy associated with a wave is directly proportional to its frequency. Hence, the higher the frequency, the shorter the wavelength and the higher the energy of the wave. Red light, then, has a lower frequency and is associated with less energy than blue light.

Why does red light bend the least?

Each beam of light has its own particular wavelength and is slowed differently by the glass. Violet light has a shorter wavelength; hence, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while the red light is bent the least.

Are longer wavelengths stronger?

Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

Why does a shorter wave bend more than a larger wave?

Shorter wave bends more than large wavelength because speed of light for short wavelength is less than speed of large wavelength in glass.and due to that refractive index for short wavelength in that particular medium is more than that of large wavelength.And according to snell’s law

Why do longer wavelengths of light diffract more?

If the hole is smaller than the wavelength, then the wavefronts coming out of the hole will be circular. Therefore, longer wavelengths diffract more than shorter wavelengths. Diffraction happens with all kinds of waves, including ocean waves, sound and light.

Why does widening the prism cause the beam to bend more?

Why does widening the prism cause the beam to bend more? When the beam of light hits the surface of a wider prism, it takes longer to get to the surface of the prism, therefore, the beam of light refracts more than the beam of light in a smaller prism. Click to see full answer.

What causes the dispersion of light by a triangular prism?

The absorption and re-emission process causes the higher frequency (lower wavelength) violet light to travel slower through crown glass than the lower frequency (higher wavelength) red light. It is this difference in n value for the varying frequencies (and wavelengths) that causes the dispersion of light by a triangular prism.
