Many phenomenons can occur: refraction, reflexion, absorption, dispersion, scattering, transmission.
When a sound wave goes from air into water, its frequency remains unchanged. However, its speed will increase, and its wavelength will decrease due to the change in the medium's properties.
wow, did you copy this offf of a science worksheet? lol and it is "it changes" and when it goes under physical change "it remains the same"

The first basic law of supply and demand is: If demand increases and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price. So the price goes up.
The frequency of light remains constant as it changes medium from air to water. However, the speed and wavelength of light will change, causing it to bend or refract.
The object is likely a lamp or a fixed light source that remains stationary when turned off and on.
When light goes through any medium other than a vacuum, its speed is normally slower than in a vacuum.
If the matter absorbs light, then its internal energy increases, and it becomes warmer. But it takes a truly huge amount of light to produce a noticeable effect ... which just goes to show how sensitive our eyes are to tiny amounts of light energy.
There is no place on the surface of the earth that goes more than six months without a sunrise. At the North and South Poles, the sun remains below the horizon for six months, and then remains above the horizon for the next six months.
That is a matter of preference. Just about any exterior color goes with a tan interior.
Matter emits light for several reasons: 1) When an electron surrounding a nucleus goes from one state to another at a lower energy, the most efficient way for energy to be conserved is for the atom to emit a photon -- ie, light. This is why a neon light gives off red light. 2) When electrons are actively vibrating due to the motions of the atoms they are connected to, Maxwell's Laws show that they will give off EM vibrations -- ie, light. This is why a fire is bright. 3) When free electrons are rapidly buzzing around, interacting with other charged particles, their accelerations due to these interactions also result in EM vibrations. This is one reason our Sun is glowing.
VSC stands for Vehicle Skid Control System. This light warns there is a problem somewhere in the vehicle skid control system or traction system. If the light goes out within 60 seconds this is normal. If the light remains on you should have it checked out. It is still safe to continue driving.
