Chapter 26, Problem 58A

(a)

To determine

To Explain:The wave which has larger wavelength: radio waves, light waves, X-rays.

Explanation of Solution

Introduction:

The relationship between wavelength and frequency is given by $\lambda =\frac{c}{\nu }$ .

Here, $\lambda$ is the wavelength, $c$ is the speed of light and $\nu$ is the frequency.

Radio wave has higher wavelength than light waves and X-rays because the frequency of radio waves is lower than light wave and X-rays.

Conclusion:

Hence, the radio waves have higher wavelength than light waves and X-rays.

(b)

To determine

To Explain:The wave which has high frequency radio waves, light waves, X-rays.

Explanation of Solution

Introduction:

The relationship between wavelength and frequency is given by $\lambda =\frac{c}{\nu }$ .

Here, $\lambda$ is the wavelength, $c$ is the speed of light and $\nu$ is the frequency.

The X-rays have higher wavelength than light waves and radio waves, because the wavelength of X-rays is much higher than radio waves and light wave.

Conclusion:

Hence, the X-rays have higherfrequency than light waves and radio waves.

(c)

To determine

To Explain:The wave which has higher velocity radio waves, light waves, X-rays.

Explanation of Solution

Introduction:

The relationship between wavelength and frequency is given by $\lambda =\frac{c}{\nu }$ .

Here $\lambda$ is the wavelength, $c$ is the speed of light and $\nu$ is the frequency.

Light waves,X-rays and radio waves have same speed in vacuum.
