I do not understand on mc question.
The de Broglie wavelength of a moving ball is calculated as 1*10^-33m. The question is : It means that the moving tennis ball.......
a)diffracts through a narrow slit
b)does not behave as a particle
c) does not display wave properties
d)is travelling at the speed of light

Hi lamalam, something only shows wave properties if its de brogile wavelength is similar in size to the object its interacting with.
What is the exact question?

Since when could a tennis ball
- diffract through a slit
- travel at the speed of light?

For the remaining two alternatives, is a tennis ball normally a wave or a particle?

If faced with having to answer a multiple choice question like this, a bit of common sense goes a long way in physics.

LOL imagine that, tennis ball diffracting through a slit.
