More Information
Visible light ranges from approximately 400 to 700 nm. Energy decreases as wavelength increases because energy is inversely related to wavelength. Increasing KV produces harder X-rays by increasing their penetration power. Wavelength is the distance between identical points in a wave. India's AC frequency is 50 Hz.
Tips
Make sure to understand the relationships between wavelength, frequency, and energy. Higher KV in X-rays means increased penetration and hardness. Remember standard values like India's AC frequency.
