a candle is located 12 cm from a concave mirror. The focal point of the mirror is 3.0 cm from the mirror, where is the image located? August 21, 2021 by Thu Thảo a candle is located 12 cm from a concave mirror. The focal point of the mirror is 3.0 cm from the mirror, where is the image located?

Answer: v = -4 cm Explanation: We have, Distance between candle and the concave mirror, u = -12 cm Focal length of the mirror is, f = -3 cm It is required to find the distance from the distance where image is located. Using mirror’s formula to find it: [tex]\dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}[/tex] v is image distance [tex]\dfrac{1}{v}=\dfrac{1}{f}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{(-3)}-\dfrac{1}{(-12)}\\\\v=-4\ cm[/tex] So, the image will formed at a distance of 4 cm.

Answer:v = -4 cm

Explanation:We have,

Distance between candle and the concave mirror, u = -12 cm

Focal length of the mirror is, f = -3 cm

It is required to find the distance from the distance where image is located. Using mirror’s formula to find it:

[tex]\dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}[/tex]

v is image distance

[tex]\dfrac{1}{v}=\dfrac{1}{f}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{(-3)}-\dfrac{1}{(-12)}\\\\v=-4\ cm[/tex]

So, the image will formed at a distance of 4 cm.
