Question

This question contains multiple parts. Make sure to read all the instructions and answer each part Part a Why is it that a column in front of the stage in a concert hall prevents you from seeing the lead violinist, but you are still able to hear the sound waves emitted by the violin? Select the correct answer O Sound waves have much shorter wavelengths than light waves and therefore are more able to bend around the column O Sound waves have much longer wavelengths than light waves and therefore are more able to bend around the column O The column resonates with the sound waves more than with the light waves O The column can transmit sound waves but not light waves O Because light travels faster than sound 0 of 3 attempts used Part b Why can AM radio waves be detected more readily than FM radio wave behind low hills or buildings? Select the correct answer O AM radio waves always have greater amplitude than FM radio waves O FM radio waves are more likely to be reflected by a large obstacle while AM radio waves are more likely to be transmitted through it O AM radio waves move faster than FM radio waves O AM radio waves have longer wavelengths, and therefore are more able to diffract around obstacles O AM radio waves have shorter wavelengths, and therefore are more able to diffract around obstacles

Answer 1

Part a

Sound waves have much longer wavelength than light waves and therefore are more able to bend around the column.

Part b

AM radio waves have longer wavelengths, and therefore are more able to diffract around obstacles.
