If energy has mass and anything that has mass cannot travel at the speed of light then how is light energy?

Energy does not have mass. Energy and mass are related to each other as stated in Einstein's famous E = mc^2. So the two are proportional, but not equal to each other.

Are there different dimensions in space and can you travel at the speed of light?
Yes, it is theorized that there are higher dimensions then the four we are familiar with. No, you cannot travel at the speed of light, no physical object that has mass can. However, that being said, you can, theoretically travel infinitely close to the speed of light which would, in turn, require an infinite amount of energy.
What travels at light speed besides engines?
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
Can light travel through air?
yes. if light didn't travel through air, then you wouldn't be able to see anything!
What type of energy is useful in light?
Light is energy. Light is made of massless particles called photons that travel at the speed of light. Photons at a given frequency carry energy equal to the Planck constant times the photon's frequency.
What role does light energy play in photosynthesis?
The name PHOTOsynthesis should tell it. It means to make from light (more specifically light energy). When the photon hits the electrons in the chloroplast, it gets charged and moves across the membrane to produce ATP.
A material that light cannot travel through?
anything opaque
Can all forms of energy travel in a vacuum?
No, all forms of energy cannot travel in a vacuum. We know that electromagnetic energy (like light or radio waves) can travel in a vacuum. So can gravity waves. But mechanical energy (like sound) cannot.
Tell why sound which is a form of energy like light cannot travel at the speed of light?
Quite simply, the two things - being "a form of energy" and travelling at a speed of light - are completely unrelated. There are other forms of energy that don't travel at all, like potential energy.
What is a material that light cannot travel through?
light can travel through anything. Light here means electromagnetic radiation, not just visible light. Visible light cannot go through anything opaque, such as metal sheets. Other types of electromagnetic radiation, like X-rays, can pass through almost anything. If you want the name ofa material where no EM radiation can pass through, it's thick lead sheet.
How are sound and light forms of energy different?
Sound is a form of mechanical energy and light is electrical. Sound moves as a longitudinal wave and lighty as a transverse wave. Sound cannot travel in free space, light can.
Is there anything that can travel faster than the speed of light?
Nothing has been found that can.However there is a theoretical prediction of particles that can ONLY travel faster than light (at 0 energy they travel infinitely fast and it takes the addition of kinetic energy to slow them down), they are called "tachyons".
How does light travel through the moon?
The moon is opaque. Light cannot travel through it.
What does light energy travel in?
waves
What are differences and similarities of sound and light?
sound can travel in vaccum but light cannot travel in vaccum
Why is visible light considered to be radiant energy and can travel through empty space but sound waves cannot travel through a vacuum?
Well light is an electromagnetic wave and it pushes itself through space ,but sound requires particles to travel through and if there are no particles for it to travel through you have no sound

What kinds of energy travel through matter?
Heat and light energy travel through space and matter
