Data Analysis and Conclusion
Answer:
28.82°
Explanation:
the equation for a diffraction grating is given by

where d is the distance between slits, m is the order of the bright fringe and lambda is the wavelength of the light. By replacing we obtain:

Then, for the third fringe the angle is 28.82°.
hope this helps!!
