A good way to think about mental and emotional health is like a tag team. Mental health refers to your ability to process information. Emotional health, on the other hand, refers to your ability to express feelings which are based upon the information you have processed.
Answer:
d = 52 μm
Explanation:
given,
wavelength of the light source (λ)= 550 nm
distance to form interference pattern(D) = 1.5 m
y = 1.6 cm = 0.016 m
width of the slits = ?
now, using displacement formula
for the first maxima, m = 1
d = 5.2 x 10⁻⁶ m
d = 52 μm
hence, the width of her slits is equal to d = 52 μm
