What Can We Learn from the Intensity Pattern of Light of 630 nm Wavelength Illuminating Two Slits?

What is the distance to the screen?

The distance to the screen from the two slits is 4.0 meters

Answer:

The distance to the screen from the two slits is 4.0 meters.

Distance is the total distance traveled by an object over a specific time interval. In this scenario, the distance to the screen is determined by the interaction of light with an object. When a light of 630 nm wavelength illuminates two slits that are 0.25 mm apart, an intensity pattern is formed on the screen behind the slits.

The distance to the screen can be calculated using the equation d = λ / (2a), where d is the distance to the screen, λ is the wavelength of the light (630 nm), and a is the separation of the two slits (0.25 mm).

Substitute the values into the equation: d = 630 nm / (2 * 0.25 mm) = 4.0 m. Therefore, the distance to the screen from the two slits is 4.0 meters.

This experiment demonstrates the phenomenon of interference of light waves, leading to the formation of an intensity pattern on the screen. By understanding the relationship between wavelength, slit separation, and distance to the screen, we can gain insights into the behavior of light.
