Question

5. Interference in thin films is mainly because of 1.Division of amplitude
3. Division of wavefronts
2. Addition of amplitude 4.Addition of wavefronts ​

Answer 1

Answer:

i think it's answer will be 3 division of wavefronts

Answer 2

The correct answer is option (3.) Division of wavefronts

Explanation:

• Interference in thin films is mainly because of Division of wavefronts.
• The type of interference that occurs when light is reflected from a thin film is dependent upon the wavelength and angle of the incident light, the thickness of the film, the refractive indices of the material on either side of the film, and the index of the film medium.
• Thin film interference can be both constructive and destructive.
• Constructive interference causes the light of a particular wavelength to increase in intensity. (It brightens a particular color like red, green, or blue.)
• Destructive interference causes the light of a particular frequency to decrease in intensity.
