Answer:
No
Explanation:
Please let me know if my answer is correct
I think you are asking if fm radio waves follow a wave motion and if so, the answer is yes
I think it’s D, mostly just because all the other ones seem like they couldn’t be the answer.
Answer:
a = 16.5 x 10⁻⁶ m = 16.5 μm
Explanation:
Here we will use the diffraction equation:
y = mλL/a
where,
y = distance between two consecutive dark fringes = 5.34 cm = 0.0534 m
m = order of diffraction = 1
λ = wavelength of light = 633 nm = 6.33 x 10⁻⁷ m
L = Distance between hair and screen = 1.4 m
a = thickness of hair = ?
0.0534 m = (1)(6.33 x 10⁻⁷ m)(1.4 m)/(a)
a = (6.33 x 10⁻⁷ m)(1.4 m)/(0.0534 m)
<u>a = 16.5 x 10⁻⁶ m = 16.5 μm</u>
Answer:
y = 2.45 x
Explanation:
given,
Let 'x' be the number of cans.
and 'y' be the total area of the room
now,
From the given statement in the question
y = 2.45 x
From the Above equation we can state that
To pain the entire room 2.45 cans of paint is required.
