The frequency of electromagnetic wave is inversely proportional to the wavelength of the wave.
The speed of a wave is directly proportional to the wavelength of the wave.
v = fλ
where;
The frequency and wavelength of electromagnetic waves is related by the following equation as shown below;
Thus, we can conclude that the frequency of electromagnetic wave is inversely proportional to the wavelength of the wave.

Answer:
32.5 m/s
Explanation:
Given:
Δy = 50 m
a = -10 m/s²
t = 2.5 s
Find: v₀
Δy = v₀ t + ½ at²
(50 m) = v₀ (2.5 s) + ½ (-10 m/s²) (2.5 s)²
v₀ = 32.5 m/s
sliding friction
rolling friction
drag
Answer:
Drag friction.
Explanation:
If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.
24 meters per second
B.
60 milligrams
C.
15 liters
D.
6 joules
The correct answer to the question is D) 6 joules.
EXPLANATION:
As per the question, four measurements are given i.e 24 m/s, 60 mg, 15 L and 6 J.
We are asked to determine the measurement which corresponds to energy.
Energy is measured in various units like joule, erg, electron volt etc.
Joule is the unit of energy in S.I system.
Hence, the correct measurement which corresponds to energy is 6 joules.
All other measurements like 24 m/s, 60 mg and 15 L are not the measurements of energy. These are the measurements of speed, mass and volume respectively.
