Electromagnetic radiation can be specified by its wavelength ( ), its frequency ( ) or its period ( ). The period is the time it
1 answer:
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:
= 33.33 cm
Explanation:
Given:
When mass, =21 kg
distance travelled is = 140 cm
When mass, =5 kg
distance travelled is = ?
Hooke's law state that within elastic limit, when an external force is applied to a body, the body gets deformed and when the force is released the gets back to its original form.
Therefore according to the question,
= 33.33 cm
Distance travelled is 33.33 cm when mass is 5 kg.
The free fall of the phone is an uniformly accelerated motion toward the ground, with constant acceleration equal to
So, assuming the downward direction as positive direction of the motion, since the phone starts from rest the distance covered by the phone after a time t is given by
And if we substitute t=2.7 s, we find the distance covered:
