Photometry is crucial for quantifying light intensity and understanding how light interacts with materials, which is essential in fields such as astronomy, Photography, and lighting design. It enables the measurement of brightness and color of light sources, aiding in the calibration of instruments and the analysis of visual environments. Additionally, photometric data informs energy efficiency standards and helps optimize lighting for human comfort and well-being. Overall, photometry plays a vital role in both scientific research and practical applications.

Flame photometry can be used for the measurement of elements which can easily be excited like Ca, K, Na, Ba, Cu etc. However due to low temperature of flame the elements like Fe can not be excited and hence not measured using Flame photometry.

Photometry is the measurement of the intensity of light emitted or received by an object, usually used to study the brightness of celestial objects like stars. Spectroscopy is the study of the interaction between light and matter, often used to analyze the composition, temperature, and motion of objects based on the light they emit or absorb.
