← ScienceWhich outcome occurs when reflective diffraction gratings experience thermal expansion?
A)Spectral resolution decreases noticeably✓
B)Grating efficiency remains optimal
C)Reflected wavelengths shift blue-ward
D)Grating sustains physical fracture easily
💡 Explanation
Thermal expansion alters groove spacing, causing constructive interference at altered exit angles, therefore spectral resolution decreases because each wavelength will diffract under a different and wider location, rather than resolution improving or shifting wavelengths, because blue shifts and ruptures happen otherwise.
