Yes, your weight appears to decrease slightly when an elevator goes down. This is because you and the elevator experience a decrease in acceleration as the elevator descends, which temporarily reduces the force acting on your body and hence, your perceived weight.
Initially, as the elevator accelerates upward, your weight reported by a scale will increase. Once the elevator reaches its final velocity, however, your weight reported by the scale will go back to normal.
When you step into an elevator and close the door, you had passed through two doors and are now standing in a box (or the elevator car) inside a vertical passageway (called the lift shaft). One door is in the walls of the floor that you got off, and the other door is part of the car itself. Inside the shaft are hoisting cables attached to the top of the car. The cables run over a sheave (pulley) connected to an electric motor at the top of the shaft. The other end of the cables is connected to a heavy steel weight called a counterweight. When the car goes up, the counterweight goes down; when the car goes down, the counterweight goes up. How the counterweight reduces to a minimum the power needed to operate the elevator ... Weight of counterweight = Weight of the car + (about) ½ of its maximum passenger load So when the elevator operates, it needs power only to lift the weight of the extra passengers in the car; the rest of the weight is balanced by the counterweight.
Your mass remains the same when the elevator goes down. However, you may feel heavier due to the acceleration experienced as the elevator descends, which creates an upward force against gravity that can make you feel heavier.
When the elevator goes up, you experience a feeling of weightlessness due to the sudden change in velocity. This causes your stomach to feel like it's dropping or rising quickly. Your body's proprioceptive system, which helps sense motion and acceleration, is temporarily confused by the sudden change, leading to the sensation of your stomach "dropping."
Wavelength times frequency equals speed (of the wave). Therefore, unless you also change the speed, if wavelength goes up, frequency goes down, and vice versa.Wavelength times frequency equals speed (of the wave).

If Jose gets on the elevator without pushing any buttons, the elevator will first go up four floors and then down six floors. This means it will end up two floors below the starting point, as it goes up four floors and then down six floors (4 - 6 = -2). Therefore, Jose will be on the second floor below where he started.
