    Radio waves diffract around building although light waves do not. The reason is that radio waves

    A)  travel with speed larger than c

    B)  have much larger wavelength than light

    C)  carry news

    D)  are not electromagnetic waves  

    Correct Answer: B

    Solution :

    Diffraction takes places when the wavelength of waves is comparable with the size of the obstacle in path. The wavelength of radio waves is greater than the wavelength of light waves. Therefore, radio waves are diffracted around building.
