The yellow arc (caution range) on an airspeed indicator indicates speeds where the aircraft may be operated only in smooth air conditions. This range extends from the normal operating limit (end of green arc) to the never-exceed speed (red line). Operations in this range require caution as turbulence or abrupt control movements could cause structural damage.

  1. green

  2. red

  3. yellow

  4. black
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A green leaf appears green because chlorophyll absorbs red and blue light while reflecting green. When illuminated with only red light, the leaf absorbs that red light (since chlorophyll absorbs red wavelengths) and reflects very little - making it appear black. The leaf cannot appear green (no green light present), red (absorbs red), or yellow (requires green+red reflection).

Multiple choice

  1. white

  2. orange

  4. red
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Red glass transmits red light while absorbing other colors. Yellow light consists of red and green wavelengths. When yellow light passes through red glass, the red component is transmitted but the green component is absorbed. The resulting transmitted light appears orange/yellow-orange, which is the visual effect of red light with a slightly modified spectrum.

C Correct answer
Explanation
