Basic questions based on aptitude, English and reasoning

Q1. What is frequencyand explain it ?
Ans. 
Frequency is the number of cycles per second in a periodic waveform.
• Frequency is measured in Hertz (Hz).

• It determines the pitch of a sound wave.

• Higher frequency means higher pitch and vice versa.

• Frequency is used in various fields like electronics, physics, and communication.

• Example: The frequency of a radio station is 98.5 MHz.

Q2. What is wavelength and explain it?
Ans. 
Wavelength is the distance between two consecutive peaks or troughs of a wave.
• Wavelength is measured in meters or nanometers.

• It determines the color of light and sound frequency.

• Shorter wavelengths have higher energy than longer wavelengths.

• Examples include the wavelength of visible light, radio waves, and X-rays.

Q3. Relationship between wavelength and frequency
Ans. 
Wavelength and frequency are inversely proportional to each other.
• Wavelength is the distance between two consecutive peaks or troughs of a wave.

• Frequency is the number of waves passing through a point in one second.

• The higher the frequency, the shorter the wavelength.

• The lower the frequency, the longer the wavelength.

• The relationship between wavelength and frequency is described by the equation: wavelength = speed of l...read more

Q4. What is pulse code modulation
Ans. 
Pulse code modulation is a digital representation of analog signals.
• PCM is used to convert analog signals into digital signals.

• It involves sampling the analog signal at regular intervals and quantizing the amplitude of each sample.

• The resulting digital signal can be transmitted or stored more efficiently than the original analog signal.

• PCM is commonly used in audio and video recording and transmission.

• It is also used i
