A point object is kept in front of a plane mirror. The plane mirror is doing S H M of amplitude 2 cm. The plane mirror moves along the x-axis and x-axis is normal to the mirror. The amplitude of the mirror is such that the object is always infront of the mirror. Find the amplitude (in cm) of SHM of the image.

A point object is kept in front of a plane mirror. The plane mirror is doing S H M of amplitude 2 cm. The plane mirror moves along the x-axis and x-axis is normal to the mirror. The amplitude of the mirror is such that the object is always infront of the mirror. Find the amplitude (in cm) of SHM of the image. (A)  (B)  (C)  (D)

If object is fixed and only plane mirror movement through ' x ' the image move through 2 x. so amplitude of SHM of image will be 4 cm.

If object is fixed and only plane mirror movement through ' x ' the image move through 2x. so amplitude of SHM of image will be 4cm.

If object is fixed and only plane mirror movement through ' $x$ ' the image move through $2 x$ . so amplitude of $S H M$ of image will be $4 c m$ .
