The distance between the two adjacent nodes = λ/2.
<h3>What is Wavelength?</h3>
A periodic wave's wavelength is its spatial period, or the length over which its form repeats. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda (λ) is frequently used to represent wavelength. The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.
The distance between the two adjacent nodes = λ/2.
for the standing wave ,the distance between any two adjacent nodes or antinodes is 1/2 λ.

<span>The answer is 6 kg the mass of the second
object. By using Inversely proportional formula it means that (14 kg) (3 m/s</span>²<span>)
= M (7 m/s</span>²<span>). Where M is the mass of the second object. For the
Newton’s second law of motion formula which is: Force = mass x acceleration, we
have:</span>
<span>F = (14 kg) (3 m/s</span>²<span>) = 42 N</span>
Therefore:
<span>42 N = M (7 m/s</span>²)
<span>M = (42 N) / (7 m/s</span>²<span>)</span>
M = 6 kg mass of the second object
The synonym for innovator and a NASA program for unmanned probes is Pioneer. Pioneer 10, launched in 1972. and Pioneer 11 launched in 1973. were the first probes that visited the outer planets and went beyond Pluto, Kuiper belt and into interstellar space. They both carry the gold-anodized aluminum plaque with naked human male and female and a map to Earth, designed by Carl Sagan, in case they are found by an extraterrestrial civilization outside the Solar system.
Answer:
Highest order: m = 1
Explanation:
Formula for solving this is;
dsin θ_m = mλ
We want to find m, thus;
m = (dsin θ_m)/λ
We are told that White light spans from 380nm - 750 nm. Thus, at maximum, λ = 750 nm.
θ_m = 90°
d = (900 lines/mm) = 9000 × 10^(-7) lines/nm
Since we want to find m, the units nm has to cancel out in the equation.
Thus, we will write d in nm/lines as (10^(7))/9000 nm/lines
Thus;
m = ((10^(7))/9000 × sin 90)/750
m = 1.48

The weight of the ball including the air inside is 1.519 N
Explanation:
First of all, we calculate the volume of the ball, which is the volume of a sphere:
where
r = 21.6 cm = 0.216 m is the radius
Substituting,
Now we can calculate the mass of the air inside the ball, knowing that its density is
Its mass is
We also know that the mass of the ball is
m = 0.100 kg
So the total mass is
Finally we can calculate the weight:
where 
is the acceleration of gravity. Substituting,
