Which photon of light in each set has the highest amount of energy?
(i) A = 7.12×10¹¹ Hz, B = 1.33×10¹⁵ Hz, C = 2.02×10¹² Hz
(ii) X = 550 nm, Y = 326 nm, Z = 428 nm

• A. (i) A = 7.12×10¹¹ Hz; (ii) X = 550 nm
• B. (i) B = 1.33×10¹⁵ Hz; (ii) Y = 326 nm
• C. (i) A = 7.12×10¹¹ Hz; (ii) Y = 326 nm
• D. (i) B = 1.33×10¹⁵ Hz; (ii) X = 550 nm
• E. (i) B = 2.02×10¹² Hz; (ii) X = 428 nm

Answer: (B)
