Question
Match the following:
- 1-d, 2-c, 3–b, 4–a
- 1–b, 2–d, 3–a, 4-c
- 1-c, 2–a, 3–d, 4–b
- 1–c, 2–d, 3–a, 4-b
Hint:
a)radiation requires a special zone.
b)These are caused by disturbance in sun's magnetic field.
c)In other words it is a brief and sudden burst of bright light.
d) Who discovered infrared light?
The correct answer is: 1-c, 2–a, 3–d, 4–b
- Energy transported by electromagnetic radiation is from radiation zone.
- The darker regions of the Sun's Photosphere is called sunspots.
- A sudden increase in the Sun's brightness is called solar flare.
- Infrared light was discovered by William Herschel.
- So, the correct option is c.
