Respuesta :
Answer: the colors come from the interference of light waves reflected from the opposite surfaces of the gasoline film. The correct option is 1.
Explanation:
These bright colours that are constructively produced under sunlight occurs due to interference of light waves reflected from the outer and inner surfaces of the thin layer of gasoline floating on water.
Thin film interference is a natural event that occurs due to reflection of interfered light waves from opposite surfaces of a thin film.
To know whether interference is constructive or destructive, you must determine if there is a phase change upon reflection. Thin film interference depends on.:
- film thickness,
-the wavelength of light, and
- the refractive indices.
For white light incident on a film that varies in thickness, you will observe rainbow colors of constructive interference for various wavelengths as the thickness varies.
The colors comes from the interference of light waves reflected from the opposite surfaces of the gasoline film.
What is interference of light waves?
The phenomenon of numerous light waves interfering with one another under particular conditions, causing the aggregate amplitudes of the waves to either rise or decrease, is known as light interference.
The interference of light waves reflected from the exterior and inner surfaces of the thin layer of gasoline floating on water produces these vivid colors that are constructively created in sunlight.
Thin film interference is a natural occurrence caused by the interference of light waves reflected from opposing sides of a thin film.
You must assess if there is a phase change upon reflection to establish whether interference is constructive or harmful. Thin film interference is determined by the following factors:
1.Thickness of the film
2.The light's wavelength
3.The indexes of refraction
When white light is incident on a film of varying thickness, the rainbow hues of constructive interference for various wavelengths will appear as the thickness varies.
Hence the colors come from the interference of light waves reflected from the opposite surfaces of the gasoline film.
