# Is the light that passes threw an oblique angle into a material of lower optical density less than the angle of refelction?

According to Snell's Law n1*sine(theta 1)=n2*sine(theta 2) where n1 and n2 is the index of refraction of two substances respectively, and theta 1 and theta 2 is The angle of r

# What is the angle of incidence when a beam of light passes at an oblique angle into a material of lower optical density?

The angle of incidence is the angle of the beam of light and the  plane surface of the object, usually measured in degrees    When a beam of light passes at an oblique

# When beam of light passes at an oblique angle into a material of lower optical density the angle of incidence is?

The angle of incidence is the angle between the optic normal and the incident ray. The angle of incidence is not equal to the angle of refraction in the second material but is

# When a beam of light passes at an oblique angle into material of lower optical density the angle of incidence is?

... greater than the angle between the beam in the material and the surface that was impinged.

# When a beam of light passes at an oblique angle into a material of lower density the angle of incidence is?

less than the angle of refraction.

# Should a material have a higher or lower density to float in water?

A material needs a lower density than water to float in water.  Ships float in water because their average density is lower than water. The average density includes the steel

# When a material is a gas it has a lower density than when it is a liquid why is this?

because the wheels in a car are pumped so when they have been brokeÂ just said,they go into a flat therefore the particles escapeso the answer to the question would be particl

# When a beam of light passes at an oblique angle into a material of lower optical density what is the angle of incidence is?

less than the angle of reflection

# If a low density light substance is surrounded by high density heavy materials which moves to the lower level?

the higher density will sink

# Does methane or water have a lower density?

At normal temperatures and pressures methane is a gas, water is a liquid.

# How do you lower density of water?

By adding Methane( a certain quantity) we can reduce it's density..

# What planets have lower density?

the gas giants- Jupiter, Saturn and the ice giants- Uranus and Neptune. These are much larger and more massive than the inner planets, but their densities (weight per unit vol

# How do you lower the density of the hydrogen gas?

You can lower the density of hydrogen (or any) gas by heating it in a container where it is free to expand, like a balloon.

# When a material is a gas does it have a lower density than when it is a liquid?

Yes, the gas phase has a much lower density than the liquid phase.
