To calculate the number of lines in the diffraction grating, we can use the formula:
number of lines = length / distance between lines
Given:
length = 3.5 x 10^-2 m
wavelength = 4997 Å (1 Å = 10^-10 m)
First, we need to convert the wavelength from Å to meters:
wavelength = 4997 x 10^-10 m
Now we can substitute the values into the formula:
number of lines = (3.5 x 10^-2 m) / (4997 x 10^-10 m)
To divide these two numbers, we can divide the numerator by the denominator and multiply by 10^10:
number of lines = (3.5 x 10^-2 m) * (10^10 m / 4997 x 10^-10 m)
number of lines = (3.5 x 10^-2) * (10^10 / 4997)
Performing the calculation:
number of lines ≈ 7000.7
Therefore, the number of lines in the diffraction grating is approximately 7000.7.
