Ångstrom and the distance between the slit and the screen is 1.2 meters, what is the wavelength of the other wavelength?

In a single slit diffraction pattern, the location of the first minimum can be determined using the equation:

sin(θ) = (m * λ) / (d)

Where:
θ is the angle of the first minimum,
m is the order of the minimum (in this case, m = 1),
λ is the wavelength of the light, and
d is the distance between the slit and the screen.

For the first minimum of red light (wavelength = 6600 Ångstrom), we can substitute the given values into the equation:

sin(θ) = (1 * 6600 Ångstrom) / (1.2 meters)

Now, we need to find the wavelength of the other light that coincides with the first maximum of the red light. For the first maximum, the angle is given by:

sin(θ) = (m * λ) / (d)

Since the first maximum occurs at the same angle as the first minimum for the other wavelength, we can equate the two equations:

(1 * λ) / (d) = (1 * 6600 Ångstrom) / (1.2 meters)

We can rearrange the equation to solve for the wavelength of the other light:

λ = (6600 Ångstrom) / (1.2 meters)

Converting Ångstrom to meters:

1 Ångstrom = 1 x 10^-10 meters

λ = (6600 x 10^-10 meters) / (1.2 meters)
λ = 5.5 x 10^-7 meters
λ = 550 nm

Therefore, the wavelength of the other light is 550 nm.
