Which of the following best explains why some materials appear white?
a) White materials reflect all wavelengths of visible light to our eyes
b) White materials absorbs all wavelengths of visible light to our eyes

Which of the following best explains what will happen to the sound of the bell when all the air is pumped out of the bell jar?
a) The bell will stop ringing because there is no medium to allow the bell to continue ringing.
b) The bell will continue to ring but it will not be heard because there is no medium to transmit the sound waves.
c) The bell will continue to ring and will still be heard because sound waves do not require medium to transmit the sound waves.
d) The bell will stop ringing eventually because the sound waves will continue to reflect off the bell jar until the energy run
