What is the function of the ultrasonic sensor in the parking assistance system?

• It measures the distance to an object using sound waves.

• It measures the distance to an object using light waves.

• It measures the distance to an object using infrared.

• It measures the distance to an object using radio waves.

The transmitter in the ultrasonic sensor emits:

• Light waves

• Infrared waves

• Sound waves

• Radio waves

The buzzer in the parking assistance system is used to:

• Indicate the temperature of the car

• Play music

• Signal the driver with a buzzing noise

• Indicate the speed of the car

The main working principle of the buzzer is based on:

• Electromagnetism

• Piezoelectric effect

• Thermoelectric effect

• Photoelectric effect

What is the purpose of the echo in the ultrasonic sensor?

• To detect sound frequency

• To measure the distance to the object

• To calculate object speed

• To identify the object's material

When the ultrasonic sensor receives the echo, it measures:

• The frequency of the sound

• The time between transmission and reception

• The amplitude of the sound wave

• The wavelength of the sound

The ultrasonic sensor consists of which two main components?

• Emitter and Detector

• Transmitter and Receiver

• Sender and Listener

• Generator and Microphone

True or False: The ultrasonic sensor can measure distance by using light waves.

• YES

• NO

True or False: The buzzer creates sound through the photoelectric effect.

• YES

• NO

Which of these is not a component of the ultrasonic sensor?

• Receiver

• Transmitter

• Amplifier

• Emitter
