Question

物理题求解答
A two-slit interference-diraction pattern is observed using light that has a wavelength equal to500 nm. The slits have a separation of 0.100 mm and an unknown width.
(a) Find the width if the fifth interference maximum is at the same angle as the first diffraction minimum.
(b) For that case, how many bright interference fringes will be seen in the central diraction maximum?

小物块加速度为12.4m/s^2,向下
木板加速度为3.6m/s^2,向上
两者相对加速度a=16m/s^2
v0^2=2al
l=0.5m
