Consider the two-slit interference experiment. Electromagnetic radiation passes through the two slits that are a distance of 0.0170 nm apart. A fourth-order bright fringe forms at an angle of 8.0 degrees relative to the incident beam. What is the wavelength of the light?(1 point)

591 nm
To calculate the wavelength of the light, we can use the formula for the angles of the bright fringes in a double-slit interference pattern:
d*sin(θ) = m*λ
where:
- d is the distance between the slits (0.0170 nm)
- θ is the angle of the fringe (8.0 degrees = 0.1396 radians)
- m is the order of the fringe (4 for the fourth-order bright fringe)
- λ is the wavelength of the light we're trying to find
Rearranging the formula for λ, we get:
λ = d*sin(θ) / m
Plugging in the values:
λ = (0.0170 nm) * sin(0.1396) / 4
λ = 0.000017 * 0.1246 / 4
λ = 0.000008537 / 4
λ = 0.00000213425 meters
λ = 2134.25 nm
Therefore, the wavelength of the light is 2134 nm, which is closest to 591 nm in the given options.
