1.301 × 10⁻¹² m

Explanation:

Step 1: Given and required data

Energy of the electromagnetic wave (E): 1.528 × 10⁻¹³ JPlanck's constant (h): 6.626 × 10⁻³⁴ J . sSpeed of light (c): 3.00 × 10⁸ m/s

Step 2: Calculate the wavelength (λ) of the electromagnetic wave

We can calculate the wavelength of the electromagnetic wave using the Planck-Einstein's relation.

E = h × c / λ

λ = h × c / E

λ = (6.626 × 10⁻³⁴ J . s) × (3.00 × 10⁸ m/s) / 1.528 × 10⁻¹³ J

λ = 1.301 × 10⁻¹² m
