The decrease in size of a person's shadow as they walk toward a lamp is due to the angle of light. As the person moves closer to the lamp, the angle of light between the person and the light source becomes smaller. This results in a smaller shadow being cast.
The size of a person's shadow changes because of the distance between the person and the light source. The closer the person is to the light source, the smaller the shadow will be. This is due to the angle of light becoming smaller as the person moves closer to the light source.
Yes, the size of the light source can affect the size of a person's shadow. A larger light source will result in a larger shadow, while a smaller light source will result in a smaller shadow. This is because a larger light source will cast a wider angle of light, resulting in a larger shadow.
No, a person's shadow cannot disappear completely. As long as there is a light source, there will always be a shadow. However, the size and darkness of the shadow may decrease to the point where it is barely visible.
Shadows get shorter during the day because of the movement of the sun. As the sun moves overhead, the angle of light changes, resulting in shorter shadows. This is why shadows are longest in the morning and evening, when the sun is closer to the horizon.
