(A) : When a mixer in a kitchen is switched on the sound from a radio in the kitchen gets nosiy. (R) : The sparking inside the mixer generates electromagnetic waves

Options

A. Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.
B. Both 'A' and ’R' are true and 'R' is not the correct explanation of 'A
C. A' is true and 'R' is false
D. 'A' is false and R' is true

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that when a mixer in a kitchen is switched on, the sound from a radio in the kitchen becomes noisy. This indicates that the operation of the mixer interferes with the radio's sound quality.

2. **Understanding the Reason (R)**:
- The reason given is that the sparking inside the mixer generates electromagnetic waves. This suggests that the mixer produces some form of electromagnetic interference (EMI) when it operates.

3. **Connecting A and R**:
- When electrical appliances like mixers are turned on, they can create sparks due to the switching of electrical currents. These sparks can emit electromagnetic waves, which can interfere with nearby electronic devices, such as radios. This interference can cause the radio to produce a noisy sound.

4. **Evaluating the Truth of A and R**:
- Both the assertion and the reason are true statements. The assertion accurately describes the phenomenon of noise in the radio when the mixer is switched on, and the reason correctly explains that this noise is due to electromagnetic waves generated by the sparking in the mixer.

5. **Conclusion**:
- Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, we conclude that the answer to the question is that both A and R are true, and R is the correct explanation for A.

### Final Answer:
Both the assertion (A) and the reason (R) are true, and R is the correct explanation for A.
