Question

THE ENERGY OF A RADIATION IS 10 ^7 EV. CALCULATE WAVELENGTH

Answer 1

10^7=10000000 so wave length =none

Answer 2

Answer:

1.23×10‐¹³

Explanation:

1ev = 1.602 × 10-¹⁹

10⁷ = 1.602 × 10-¹⁹ ×10⁷

Using Formula _____

E = h×c ÷ wave length

wave length = 6.6 × 10-³⁴ ×3 × 10⁸ ÷ 1.602 × 10-¹⁹ ×10⁷

answer is = 1.23×10-¹³
