Answer:
The relation between f,T,λ
f=
λ =
λ =
Explanation:
Let us consider,
wavelength as λ
frequency as f
time period as T
The <em>time period</em> is defined as time taken by the wave to complete one oscillation or number or seconds to complete one full oscillation.
The <em>frequency </em>is defined as number of oscillation done per second.
The <em>wavelength</em> is defined as distance between two successive crests or trough. in a wave.
<em>The frequency and time period are reciprocals. </em>
<em>The wavelength and frequency are reciprocals ie larger the wavelength shorter is the frequency</em>
The relation between frequency and time period is f =.
The relation between wavelength and frequency is λ =
where v is velocity of light.
The relation between wavelength and time period is λ =

Answer:
The ratio of the diameter of iron to Cu is;
Explanation:
R=(ρL)/A
- R is resistance,
- L is length,
- A is area,
- ρ is resistivity
- d is diameter
from the question the two materials have the same resistance per unit length.
for iron =
for copper
This means we can equate ρ/A for both materials.
re-arranging the equation we have,
Answer:
the spring constant k =
the value for the damping constant
Explanation:
From Hooke's Law
Thus; the spring constant k =
The amplitude is decreasing 37% during one period of the motion
Therefore; the value for the damping constant
