The wavelength of the light is 320.23 nm.
Light passing through a double slit with separation is given as
d = 3.33 × 10⁻⁵ m.
Line number m = 1
Angle θ = 0.551°
How wavelength is calculated and what is the wavelength of the light?
The distance between two sound waves i.e., crest and trough is called the wavelength.
Human eye can detect the wavelength of about 380 nm to 700 nm.
To find the wavelength, here we use the formula as,
sin θ = Line number × λ ÷ ( distance )
By substituting all the values,
Sin ( 0.551 ) = 1 × λ ÷ ( 3.33 × 10⁻⁵)
Rearranging the equation,
λ= (Sin ( 0.551 ) × ( 3.33 × 10⁻⁵) ) ÷ (1)
λ = 320.23 nm.
Thus, wavelength λ of the light is 320.23 nm.
