The array of colors observed when viewing films of soap are caused by the interference, and from the reflections of light from two nearby surfaces (outer surface and inner surface). Among the choices, the closest answer would be B. reflection, refraction, and interference.
There are two planets with no moons, Mercury and Venus. After that the order<span> is Earth (1), Mars (2), Neptune (14), Uranus (27), Saturn (62), and Jupiter (67).
so its A
</span>
<span>
A= 5 i − 3 J and B = −i − 6 j
A+ B
=5 i − 3 j −i − 6 j = 4 i - 9 j ---answer
A - B
= 5 i − 3 j + i + 6 j = 6 i + 3j ---answer
|A+B|
= sq root [ 16 + 81] = 9.848 ---answer
|A - B|
= sq root [ 36 + 9] = 6.708 ---answer
directions of A+ B
= tan (-1) -9 /4 = - 66 deg --answer
direction of A- B
= tan (-1) 3 /6 = 26.56 deg --answer</span>
Answer:
Because of the lens
Explanation:
The lens have a problem and it's the same that the atmosphere offers, if you look at the moon in the night while a cloud is close (it looks better on full moon) you can see an aura wrapping the moon, that happens because the clouds in the atmosphere divide the light and make that aura. The same happens with the lens of some microscopes, that's why the most expensive microscopes are avoiding the use of lens.
