The tactile system is actually made up of two distinct skin senses.
Ludmilka [50]

The tactile system is actually made up of two distinct skin senses; protective and the discriminative system. The function of the protective system is to alert us to harmful stimuli. The receptors of the system are the hairs of our skin, head and genitals. The discriminative system is to show us what we are touching, where on our bodies is touching us and what are touching us. The receptors for his system are the hands, fingers, soles of feet and mouth and tongue.

an object 50 cm high is placed 1 m in front of a converging lens whose focal length is 1.5 m. determine the image height (in cm)
Juli2301 [7.4K]

Given :

An object 50 cm high is placed 1 m in front of a converging lens whose focal length is 1.5 m.

To Find :

the image height (in cm).

Solution :

By lens formula :

\dfrac{1}{v} - \dfrac{1}{u} = \dfrac{1}{f}

Here, u = - 100 cm

f =  150 cm

\dfrac{1}{v} - \dfrac{1}{-100} = \dfrac{1}{150}\\\\v = - 300 \ cm

Now, magnification is given by :

m = \dfrac{v}{u} = \dfrac{h_i}{h_o}\\\\h_i = \dfrac{300}{100}\times 1\\\\h_i = 3 \ m

Therefore, the image height is 3 m or 300 cm.
