Two thin slits with separation of .0250mm are placed over monochromatic orange laser light at 610.nm. What is the small angle measurement from the central maximum (zero degrees, inline with the source) to the first maximum?

To find the small angle measurement from the central maximum to the first maximum in a double-slit interference experiment, you can use the formula:
θ = λ / d
where:
θ is the angle,
λ is the wavelength of the light, and
d is the separation between the slits.
Given:
λ = 610 nm = 610 × 10^(-9) m (convert from nm to meters),
d = 0.0250 mm = 0.0250 × 10^(-3) m (convert from mm to meters).
Plugging the values into the formula:
θ = (610 × 10^(-9) m) / (0.0250 × 10^(-3) m)
To simplify the calculation, we can cancel out the common factors of 10^(-9) and 10^(-3) from both the numerator and denominator:
θ = 610 / 0.0250
Evaluating the division gives:
θ ≈ 24.4
Thus, the angle measurement from the central maximum to the first maximum is approximately 24.4 degrees.
