Question

suppose the wavelength of the light is 490 nm . how much farther is it from the dot on the screen in the center of fringe e to the left slit than it is from the dot to the right slit?

Answer 1

In a double-slit interference pattern, the distance between the dot on the screen in the center of fringe e and the left slit is the same as the distance between the dot and the right slit.

Step-by-step explanation:

The distance between the dot on the screen in the center of fringe e and the left slit is equal to the distance between the dot on the screen and the right slit in a double-slit interference pattern. This is because the fringes produced by the interference of light waves from the two slits are equidistant. So, the distance from the dot to each slit is the same.

Answer 2

To find the difference in distance between the dot on the screen and the left slit and the dot to the right slit, we can use the formula d = (λ × L) / d, where d is the distance between the dot and each slit, λ is the wavelength of the light, and L is the distance between the screen and the slits. The exact difference will depend on the specific values of λ and L, but it will likely be very small, on the order of nanometers or micrometers.

Step-by-step explanation:

To find the distance between the dot on the screen in the center of fringe e to the left slit and the dot to the right slit, we can use the formula:

d = \frac{\lambda \cdot L}{d}

where d is the distance between the dot and each slit, \lambda is the wavelength of the light, and L is the distance between the screen and the slits.

In this case, the wavelength of the light is 490 nm, and we need to find the distance between the dot and each slit. Without knowing the values of \lambda and L, we can't calculate the exact difference. However, we can say that the difference between the two distances will be very small, on the order of nanometers or micrometers.
