This shielding is a maximum for UV light having a wavelength of 295nanometers. What is the frequency in hertz of this particular

LUCKY_DIMON [66]

Answer:

$\large \boxed{\text{1.016 $\times 10^{15}$ Hz}}$

Explanation:

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

fλ = c

1. Convert nanometres to metres

295 nm = 295 × 10⁻⁹ m

2. Calculate the frequency

$\begin{array}{rcl}f \times 295 \times 10^{-9} \text{ m}& =& 2.998 \times 10^{8} \text{ m$\cdot$s$^{-1}$}\\\\f & = & \dfrac{2.998 \times 10^{8} \text{ m$\cdot$s$^{-1}$}}{295 \times 10^{-9}\text{ m}}\\\\& = &1.016 \times 10^{15}\text{ s}^{-1}\\& = &\large \boxed{\textbf{1.016 $\mathbf{\times 10^{15}}$ Hz}}\end{array}$
