Answer:
The distance of image formed by the concave mirror is at 10.495 cm.
Explanation:
Since we know that a plane mirror forms image at a distance behind the mirror at which the object is placed in front of the mirror thus we have.
Image formed by the plane mirror is at a distance of 12.5 cm behind the plane mirror.
The image formed by the plane mirror is at a distance of 12.5 + 25.0 = 37.5 cm from the pole of the concave mirror.
Thus by mirror formula we have
[tex]\frac{1}{v}+\frac{1}{u}=\frac{1}{f}[/tex]
Using the standard sign convention we have
u = location of object = -37.5 cm
f = focal length of mirror = -8.20 cm
Thus using the given values we obtain
[tex]\frac{1}{v}+\frac{1}{-37.5}=\frac{1}{-8.2}\\\\\therefore v=-10.495cm[/tex]
Thus the image is formed at a distance of 10.495 cm from the pole of mirror towards left of mirror.
Answer:
Sol: - I1: Reflexión a la distancia del primer espejo del objeto = 5 cm a la derecha ==> distancia de la imagen = 5 cm a la izquierda Ahora, I2: Reflexión al espejo 2 distancia del objeto = 20-5 = 15 cm a la izquierda == > distancia de imagen = 15 cm a la derecha Ahora, I3: la imagen I2 será como objeto para el espejo 1 distancia de objeto = 15 + 20 = 35 cm a la derecha ==> distancia de imagen = 35 cm a la izquierda Ahora, I4: I1 la imagen será como objeto para el espejo 2 distancia del objeto = 5 + 20 = 25 cm a la izquierda ==> distancia de la imagen = 25 cm a la derecha Ahora, I5: la imagen I4 será como objeto para la distancia del espejo 1 ...
