Xrays are used to diagnose diseases of internal body organs. what is the frequency of an x ray with a wavelentgh of 1.15*10^-10

2.31 EHz

Explanation:

The formula relating the frequency (f) and wavelength (λ) is

fλ = c                                        Divide both sides by λ

f = c/λ

c = 2.998 × 10⁸ m·s⁻¹

λ = 1.15 × 10⁻¹⁰ m                     Calculate f.

f = 2.998 × 10⁸/1.15 × 10⁻¹⁰

f = 2.61 × 10¹⁸ s⁻¹ = 2.61 EHz

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
