Answer:
Speed = 7.04434 m/s
Explanation:
Given that:
The radius of the circle = 6.5 m
The expression for the calculation of circumference is shown below as:
Thus,
Time taken = 5.8 seconds.
Thus, The speed is:
So,
<u>Speed = 7.04434 m/s</u>
Answer:
Violet color has the highest frequency.
Explanation:
Light: it can behave as particle and wave. It has both natures. Frequency is the characteristic of the wave. It is defined as how many waves can pass through at a point in a given interval of time. It is measured in hertz.
Red: It lies in the visible region of the light. it has the lowest frequency in the visible region of the light.
Violet: It lies in the visible region of the light. Every wave has some energy. The energy of the wave is directly proportional to the frequency of the wave. More the energy of the wave then more will be the frequency of the wave. Violet color has more energy. It has the highest frequency.
