A gamma ray (a pulse of electromagnetic energy)has a frequency of 2.42 $\times$ 10²⁰ Hz.What is the ratio of its wavelength to the radius of the nucleus which produced it (radius = 5.0 $\times$10^-13 cm)? A)248 B)39.4 C)1.21 × 10⁸ D)0.015

Question

Quizplus · Accepted Answer

The wavelength of a gamma ray is given by the equation:$$\lambda = \frac{c}{f}$$where:* $$\lambda$$ is the wavelength in meters* $$c$$ is the speed of light in meters per second* $$f$$ is the frequency in hertzThe radius of a nucleus is typically on the order of 10^-13 cm.So, the ratio of the wavelength of a gamma ray to the radius of the nucleus which produced it is:$$\frac{\lambda}{r} = \frac{c}{fr} = \frac{3 	imes 10^8 m/s}{(2.42 	imes 10^{20} Hz)(5 	imes 10^{-13} cm)} = 248$$
