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.
Standard sea level pressure by definition equals 760 mm (29.92 inches) of mercury
Answer:
Electric Motor
Explanation:
There are mainly two types of machines for inter-conversion between mechanical energy and electrical energy as under:
- Motor
- Generator
Motor is a device which converts electrical energy into a mechanical whereas generator does the exact opposite of motor.
There are 2 types of motors:
AC Motor - Converts alternating current into mechanical energy
DC Motor - Converts direct current into mechanical energy
