Expert's answer

1. Electromagnetic radiation travels through vacuum at a speed of 2.998x10

2. The 6-meter wavelengh corresponds to ν = c/λ = 2.998×10

3. The light that has a wavelength of λ = 3.25×10

ν = c/λ =2.998×10

4. The frequency of a photon that has an energy of 4.15 × 10

ν = E/h = 4.15×10

5. The wavelength of a photon that has energy of 4.15 × 10

λ = hc/E = (6.63×10

^{8}m/s.2. The 6-meter wavelengh corresponds to ν = c/λ = 2.998×10

^{8}/6 = 5x10^{7}s^{-1}or 50 MHz3. The light that has a wavelength of λ = 3.25×10

^{-6}cm corresponds toν = c/λ =2.998×10

^{8}/3.25×10^{-8}= 9.224×10^{15}s^{-1}4. The frequency of a photon that has an energy of 4.15 × 10

^{-18}J isν = E/h = 4.15×10

^{-18}/(6.63 × 10^{-34}) = 6.26 × 10^{15}s^{-1}5. The wavelength of a photon that has energy of 4.15 × 10

^{-18}J isλ = hc/E = (6.63×10

^{-34}x 2.998×10^{8})/(4.15×10^{-18}) = 4.793 × 10^{-8}m or 47.93 nmNeed a fast expert's response?
