How focal length of a lens change when apparatus immersed in water?
The focal length of a lens decreases when it is immersed in water due to the change in the refractive index of the medium. This change causes the light rays passing through the lens to bend differently, altering the focal point of the lens.
Why does a coin appear bigger in size when immersed in water?
When a coin is immersed in water, the water refracts the light that passes through it. This refraction makes the coin appear bigger and closer to the surface of the water than it actually is. It's an optical illusion caused by the way light travels through different mediums.
Why does the stick appear to be broken?
The stick appears to be broken due to light refraction at the interface between the air and water, causing the light rays to bend. This bending of light makes the stick appear disjointed at the point where it enters the water.
Why a pen bend when you dip it in the water?
When you dip a pen in water, the water molecules adhere to the pen's surface. This causes the fibers in the pen to absorb water and expand unevenly, resulting in the bend. Additionally, the surface tension of water can also contribute to the bending effect.
When you stick a metal or plastic spoon in extreamely hot water which one will bend more?
The plastic spoon is more likely to bend in extremely hot water compared to a metal spoon. This is because plastic has a lower melting point than metal, which causes it to soften and deform more easily under high temperatures. Metal is generally more heat-resistant and maintains its shape better under extreme heat.

How do you curve a mini stick?
You curve it by putting it in boiling water. take an oven mit and bend it. immediatly put it in cold water.

The stick appears to be broken due to light refraction at the interface between the air and water, causing the light rays to bend. This bending of light makes the stick appear disjointed at the point where it enters the water.
Will fizzy drinks damage your retainer?
yes, it will attack the metal causing it to bend and be no use at all, stick to the water pal!
Why a pen bend when you dip it in the water?

Will soaking a wooden stick make it bend?
no
Can you bend a stick without breaking it?
Yes
When you stick a metal or plastic spoon in extreamely hot water which one will bend more?
The plastic spoon is more likely to bend in extremely hot water compared to a metal spoon. This is because plastic has a lower melting point than metal, which causes it to soften and deform more easily under high temperatures. Metal is generally more heat-resistant and maintains its shape better under extreme heat.
Why does a piece of glass of irregular shape becomes invisible when it is immersed in liquid of same refractive index?
When light passes from one medium to another with the same refractive index, there is no change in the speed of light, and the light does not bend or refract. This causes the light to pass through without changing direction, making the irregularly shaped glass appear invisible when immersed in the liquid of the same refractive index.
When a wave travels from air into water it will bend away from the normal?
When a wave travels from air into water, it will slow down due to the increase in the water's density. This change in speed causes the wave to refract and bend away from the normal, which is an imaginary line perpendicular to the water's surface at the point of incidence.
What is the muscle that causes parts of the body to bend?
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
