How to Calculate the Wavelength of Light and Increase Fringe Spacing

How can you calculate the wavelength of light based on the interference pattern on the screen?

What is the formula to determine the wavelength of light in this scenario?

What is the method to increase the fringe spacing on the screen with a specific distance?

Answer:

(a) The wavelength of light can be calculated using the formula:

λ = d * λ / (y2 - y1)

Where d represents the distance between the slits, λ is the wavelength of light, and (y2 - y1) is the distance between the edges of the screen. By applying this formula, we can determine the wavelength of the light in the given scenario.

(b) To increase the fringe spacing on the screen to a specific distance, the formula can be employed:

distance = d * λ / (y2 - y1)

By solving this equation, the required distance at which the screen should be placed can be calculated to achieve the desired fringe spacing.

In the provided scenario, the wavelength of light can be calculated by measuring the distance between two bright lines on the interference pattern produced on the screen. This distance is used to determine the wavelength using the formula mentioned earlier.

Wavelength is a crucial concept in physics, particularly when dealing with electromagnetic radiation like light. It is the distance between two successive wave crests or troughs and plays a significant role in determining the behavior of waves. For example, in the case of visible light, different wavelengths correspond to different colors, with purple light having a shorter wavelength than red light.

Furthermore, wavelength is inversely proportional to wave frequency, meaning that higher frequency waves have shorter wavelengths. This relationship is fundamental in understanding the characteristics of various types of waves, whether they are light waves, sound waves, or other forms of electromagnetic radiation.

By following the calculations and formulas provided, you can accurately calculate the wavelength of light in a given interference pattern scenario and determine the necessary adjustments to achieve the desired fringe spacing on the screen.
