For this case we have by definition:
v = λf
We observe that we have a linear relationship, where λ is the constant of proportionality.
We have then:
- <em>v: speed of propagation of the wave
</em>
- <em>λ: wavelength
</em>
- <em>f: frequency
</em>
Answer:
The variable that is directly proportional to the frequency is λ, the wavelength.
I don’t think I can do that because I’m going out and I can not take her out and do it because I have to work because I’m not sure what if you do not answer question because I answer answer text please please text please answer question answer answer question question answer please thank the god that he shows me please answer answer please answer me question answer question because you lord lord please please thank
Answer:
1 x 10¹⁸cm
Explanation:
Given parameters:
Velocity of light = 300,000,000cm/s
Unknown:
Distance in centimeters = ?
Solution:
To solve this problem,
The velocity of light is 3 x 10⁸m/s
Velocity = 
Distance = velocity x time = 3 x 10⁸m/s x 3.2 x 10⁷s
= 9.6 x 10¹⁵m
To cm;
100cm = 1m
Distance = 9.6 x 10¹⁵ x 10² = 9.6 x 10¹⁷cm = 1 x 10¹⁸cm
The sun would reach earth and we can use solar panels to soak in the sun. Then the sun energy from the solar panels are some how turned into electricity with complex stuff
