Question

State how the wavelength of violet light in air differs from the wavelength of red light in

air.

Answer 1

Step-by-step explanation:

The wavelength of violet light in air is shorter than the wavelength of red light in air. This is because different colors of light have different wavelengths.

When light passes through a medium, such as air, it can be affected by the properties of that medium. In general, different colors of light have different speeds and wavelengths when traveling through air.

Violet light has a shorter wavelength compared to red light. This means that the distance between two similar points on successive waves of violet light is smaller than the distance between two similar points on successive waves of red light. In other words, violet light has waves that are closer together in air.

The difference in wavelength between violet and red light is mainly due to their frequencies. Violet light has a higher frequency compared to red light. Frequency and wavelength are inversely proportional, meaning higher frequency corresponds to shorter wavelength and vice versa.

Hence, the wavelength of violet light is shorter than the wavelength of red light in air.

Answer 2

The wavelength of violet light (roughly 400 nm) and the wavelength of red light (roughly 650 nm) differ because they have different frequencies, and therefore, have different energy levels. The shorter the wavelength of a light wave, the more energy it carries per photon. This means that violet light has more energy per photon than red light. This also means that violet light has a higher frequency than red light, and therefore, it has a shorter wavelength.
