Receiver — Science definition

Defined in 2 courses:

Object on which a named force acts. (Physical Science: Matter, Forces & Energy)
Object or system responding to the arriving disturbance. (Physical Science: Matter, Forces & Energy)

Where it is taught

Interaction Pairs & Force Diagrams — Forces, Physical Science: Matter, Forces & Energy, Grade 8
Sound Sources, Vibrations & Receivers — Waves, Sound & Light, Physical Science: Matter, Forces & Energy, Grade 8

In use

A source is the vibrating object producing the disturbance, and a receiver is the object that responds elsewhere.

Questions using receiver

Problem 1

Which receiver belongs in a cart diagram?

Answer and explanation

The cart. Forces exerted on the table or on Earth belong in separate diagrams, even though they are connected interactions.

Response criteria

Use the supplied conditions and relevant evidence.
Explain the scientific mechanism or calculation.
State a meaningful limitation or testable next step.

Problem 2

Illustrative sources A/B/C have amplitudes 1/3/1 mm and complete 4/4/6 cycles respectively in 0.02 s. Compare frequency and amplitude and explain what a receiver prediction would need.

Answer and explanation

A and B are 200 Hz, while C is 300 Hz. B has three times A’s amplitude; C has A’s amplitude but higher frequency. Frequency and amplitude are distinct. Predicting received sound also needs distance, medium, losses and receiver response. The source records alone do not establish an exact perceived loudness.
