When platinum is heated at 1300°C, then its color turns
Correct answer: A. cherry colour
- A. cherry colour
- B. yellow colour
- C. red colour
- D. dull red colour
Explanation
When platinum is heated at around 1300°C, it emits a bright red light, which appears as a cherry color. This phenomenon is due to incandescence, where a material emits light due to its high temperature.Incorrect Options and Explanations: (b) yellow colour - At 1300°C, platinum emits a cherry-red color, not yellow. (c) red colour - The color emitted by platinum at 1300°C is closer to a cherry-red color rather than a standard red color. (d) dull red colour - The color emitted by platinum at high temperatures like 1300°C is not dull but rather bright and intense.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
