True
Variables is changing. It is any factor, trait or condition that can exist in differing amounts or types. An experiment has three types: Independent, Dependent and Controlled.
Answer:
200 m
Explanation:
Path difference of waves from A and B = 100m
For destructive interference
Path diff = ( 2n+ 1 ) λ / 2
100 = ( 2n+ 1 ) λ / 2
λ = 200 / ( 2n+ 1 )
For maximum λ , denominator should be smallest which is possible for
n =0
λ = 200 / 1
= 200 m
Answer:
the law of motion
Explanation:
because the wheels are moving it means motion i am not sure which number law it is but I believe that it is 2nd but u should look it up to be safe
Answer
given,
width of slit, d = 0.08 mm
d = 8 x 10⁻⁵ m
light of two wavelength
I₁= 446 nm
I₂ = 662 nm
a) angles at which the third dark fringe
m = 3 , I₁= 446 nm
C = 0.958°
m = 3 , I₁= 662 nm
C = 1.423°
b) angles at which the third dark fringe
m = 1 , I₁= 446 nm
C = 0.319°
m = 1 , I₁= 662 nm
C = 0.474°
