Question
What are the wavelengths of clectromagnetic waves in free space that have frequencies of (a) $5.00 \times 10^{19} \mathrm{Hz}$ and (b) $4.00 \times 10^{9} \mathrm{Hz}$ ?
Step 1
00 \times 10^{8} \mathrm{m/s}$. The relationship between the speed of light (c), frequency (f), and wavelength (λ) is given by the equation $c = f \lambda$. Show more…

Electromagnetic Waves The speed of electromagnetic waves (which include visible light, radio, and $x$ -rays) in vacuum is $3.0 \times$ $10^{8} \mathrm{~m} / \mathrm{s}$. (a) Wavelengths of visible light waves range from about $400 \mathrm{~nm}$ in the violet to about $700 \mathrm{~nm}$ in the red. What is the range of frequencies of these waves? (b) The range of frequencies for shortwave radio (for example, FM radio and VHF television) is $1.5$ to $300 \mathrm{MHz}$. What is the corresponding wavelength range? (c) X-ray wavelengths range from about $5.0 \mathrm{~nm}$ to about $1.0 \times$ $10^{-2} \mathrm{~nm}$. What is the frequency range for $\mathrm{x}$ -rays?
